;; About php.ini ;;

; This file must be named 'php.ini' and placed in the directory specified by the PHPINIDir directive in httpd.conf.
; The latest version of php.ini can be viewed at the following two locations:
; http://cvs.php.net/viewvc.cgi/php-src/php.ini-recommended?view=co
; http://cvs.php.net/viewvc.cgi/php-src/php.ini-dist?view=co



;; Syntax;;

; The syntax of this file is very simple. Whitespace characters and lines starting with semicolons are simply ignored.
; Section titles (eg: [php]) are also simply ignored, even though they may have some meaning in the future.

; The format of the setting directive is as follows:
; directive = value
; The directive name (directive) is case-sensitive! So "foo=bar" is different from "FOO=bar".
; Value can be:
; 1. A string delimited by quotation marks (such as: "foo")
; 2. A number (integer or floating point number, such as: 0, 1, 34, -1, 33.55)
; 3. A PHP constant (such as: E_ALL, M_PI)
; 4. An INI constant (On, Off, none)
; 5. An expression (such as : E_ALL & ~E_NOTICE)

; Expressions in the INI file only use: bitwise operators, logical NOT, parentheses:
; | bitwise or
; & bitwise and
; ~ Bit NOT
; ! Logical NOT

; The Boolean flag uses On to indicate on and Off to indicate off.

; An empty string can be represented by writing nothing after the equal sign, or using the none keyword:
; foo = ; Set foo to an empty string
; foo = none ; Set foo to the empty string
; foo = "none" ; Set foo to the string 'none'

; if you use dynamic expansion (PHP extension or Zend extension) in the directive value constants in
; then you can only use these constants after loading these dynamically expanded command lines.



;; httpd.conf ;;

; The value of php.ini can be overridden in httpd.conf for a specific virtual host or directory for more flexibility. Configuration:
; php_admin_value name value; Set non-bool type instructions, set value to none to clear the previous settings
; php_admin_flag name on|off; Only used to set bool type instructions
; [Tip] Because many instructions do not allow setting using php_value/php_flag, it is not recommended to use these two.

; PHP constants (such as E_ALL) can only be used in php.ini, and the corresponding mask value must be used in httpd.conf.

;[Updated on 2008-3-2]
;============================== ================================================== ==========
;;==================================== ==Detailed explanation of configuration instructions========================================
;= ================================================== =======================================
; Settings for each command below The values ​​are the same as the built-in defaults in PHP-5.2.5.
; That is, if 'php.ini' does not exist, or you delete some lines, the default value will be the same.

;;;;;;;;;;;;;;
;; Apache ;;

[Apache]
; Only when using PHP as an Apache module efficient.

child_terminate = Off
; Whether the PHP script is allowed to use the apache_child_terminate() function to terminate the child process after the request ends.
; This directive is only available when PHP is installed as a module of Apache1.3 on UNIX platforms. It does not exist in any other case.

engine = On
; Whether to enable the PHP parsing engine.
; Tip: You can turn on or off the PHP parsing engine based on the directory or virtual host in httpd.conf.

last_modified = Off
; Whether to place the last modified time of the PHP script in the Last-Modified response header.

xbithack = Off
; Whether to parse as a PHP executable byte group regardless of the end of the file.



;; PHP Core;;


[PHP-Core-DateTime]
; The first four configuration options are currently only used for date_sunrise() and date_sunset() function.

date.default_latitude = 31.7667
; Default latitude

date.default_longitude = 35.2333
; Default longitude

date.sunrise_zenith = 90.583333
; Default Sunrise zenith

date.sunset_zenith = 90.583333
; Default sunset zenith

date.timezone =
; Used for all dates and times when the TZ environment variable is not set The function's default time zone.
; Mainland China should use "PRC"
; The priority order of application time zones is:
; 1. The time zone set with the date_default_timezone_set() function (if set)
; 2. TZ environment variable (if not empty)
; 3. The value of the instruction (if set)
; 4. PHP's own guess (if the operating system supports it)
; 5. If all of the above If unsuccessful, use "UTC"


[PHP-Core-Assert]

assert.active = On
; Whether to enable assert() assertion evaluation

assert.bail = Off
; Whether to abort the execution of the script when a failed assertion occurs

assert.callback =
; The callback function executed when a failed assertion occurs

assert .quiet_eval = Off
; Whether to use quiet evaluation (do not display any error information, equivalent to error_reporting=0).
; If turned off, the current error_reporting directive value is used when evaluating assertion expressions.

assert.warning = On
; Whether to issue a warning for each failed assertion


[PHP-Core-SafeMode]
; Safe mode is to solve the problem of sharing Established for server security issues.
; But trying to solve this problem at the PHP layer is structurally unreasonable.
; The correct approach should be to modify the web server layer and operating system layer.
; Therefore, the safe mode is abolished in PHP6 and security protection based on open_basedir is used.
; This part of the instructions has been completely deleted in PHP6.

safe_mode = Off
; Whether to enable safe mode.
; When opened, PHP will check whether the owner of the current script is the same as the owner of the file being operated.
; If they are the same, the operation is allowed, if they are different, the operation is denied.

safe_mode_gid = Off
; In safe mode, a UID comparison check is performed by default when accessing files.
; But in some cases strict UID checking is not suitable, and loose GID checking is enough.
; If you want to relax it to only do GID comparison, you can turn this parameter on.

safe_mode_allowed_env_vars = "PHP_"
; A comma-separated list of prefixes for environment variables that users can only change in safe mode.
; Allows users to set certain environment variables, which may lead to potential security vulnerabilities.
; Note: If this parameter value is empty, PHP will allow users to change any environment variables!

safe_mode_protected_env_vars = "LD_LIBRARY_PATH"
; List of environment variables (comma separated) that users cannot change in safe mode.
; These variables are protected even when the safe_mode_allowed_env_vars directive is set to allowed.

safe_mode_exec_dir = "/usr/local/php/bin"
; In safe mode, only executable programs in this directory are allowed to be executed by the function of the system program.
; These functions are: system, escapeshellarg, escapeshellcmd, exec, passthru,
; proc_close, proc_get_status, proc_nice, proc_open, proc_terminate, shell_exec

safe_mode_include_dir =
; In safe mode, When files in this group directory and its subdirectories are included, UID/GID checking will be skipped.
; In other words, if the value here is empty, any file whose UID/GID does not match is not allowed to be included.
; The directory set here must already exist in the include_path directive or be included with a full path.
; Use colons (semicolons under Win) to separate multiple directories.
; The specified restriction is actually a prefix, not a directory name,
; that is, "/dir/incl" will allow access to "/dir/include" and "/dir/incls"
; If you wish to restrict access to a specific directory, add a trailing slash.


[PHP-Core-Safe]

allow_url_fopen = On
; Whether to allow remote files to be opened

allow_url_include = Off
; Whether to allow include /require remote files.

disable_classes =
; This directive accepts a comma separated list of class names to disable specific classes.

disable_functions =
; This directive accepts a comma separated list of function names to disable specific functions.

enable_dl = On
; Whether to allow the use of the dl() function. The dl() function only works when PHP is installed as an apache module.
; Disabling the dl() function is mainly for security reasons, because it can bypass the restrictions of the open_basedir directive.
; Always disable the dl() function in safe mode, regardless of how it is set here.
; This directive has been deleted in PHP6, which is equivalent to setting it to Off.

expose_php = On
; Whether to expose the fact that PHP is installed on the server (add its signature in the http header).
; It poses no direct security threat, but it lets the client know that PHP is installed on the server.

open_basedir =
; Limit all files that PHP allows to operate (including the file itself) to this group of directory lists.
; When a script attempts to open a file outside the specified directory tree, it will be rejected.
; All symbolic links are resolved, so it is not possible to circumvent this restriction through symbolic links.
; The special value '.' specifies that the directory where the script is stored will be used as the base directory,
; but this is somewhat dangerous because the script's working directory can be easily changed by chdir().
; For shared servers, it will be very useful to flexibly set this directive in httpd.conf for different virtual hosts or directories.
; Use semicolons to separate directories on Windows and colons on UNIX systems.
; When used as an Apache module, the open_basedir path in the parent directory will be automatically inherited.
; The specified restriction is actually a prefix, not a directory name,
; In other words, "/dir/incl" will allow access to "/dir/include" and "/dir/incls",
; If you wish to control access to a specific directory, add a trailing slash.
; The default is to allow all files to be opened.

sql.safe_mode = Off
; Whether to use SQL safe mode.
; If on, database connection functions that specify default values ​​will use these default values ​​instead of supported parameters.
; For the connection function of each different database, please refer to the corresponding manual page for its default value.


[PHP-Core-Error]

error_reporting = E_ALL & ~E_NOTICE
; The error reporting level is the superposition of bit fields, it is recommended to use E_ALL | E_STRICT
; 1 E_ERROR Fatal runtime error
; 2 E_WARNING Runtime warning (non-fatal error)
; 4 E_PARSE Compile time parsing error
; 8 E_NOTICE Runtime reminder (often a bug, it may be intentional )
; 16 E_CORE_ERROR Fatal error during PHP startup initialization
; 32 E_CORE_WARNING Warning (non-fatal error) during PHP startup initialization
; 64 E_COMPILE_ERROR Fatal error during compilation
; 128 E_COMPILE_WARNING compile-time warning (non-fatal error)
; 256 E_USER_ERROR user-defined fatal error
; 512 E_USER_WARNING user-defined warning (non-fatal error)
; 1024 E_USER_NOTICE user-defined Definition reminder (often a bug, may also be intentional)
; 2048 E_STRICT Coding standardization warning (recommend how to modify for forward compatibility)
; 4096 E_RECOVERABLE_ERROR Near-fatal runtime error, if not caught Treated as E_ERROR
; 6143 E_ALL All errors except E_STRICT (8191 in PHP6, including all)
; You can also use 2147483647 (all binary bits are all 1) to open various errors that may occur now or in the future Errors

track_errors = Off
; Whether to save the latest error or warning message in the variable $php_errormsg.

display_errors = On
; Whether to display error messages as part of the output.
; On the final published web site, it is strongly recommended that you turn off this feature and use error logging instead (see below).
; Turning this feature on in the final published web site may expose some security information,
; such as file paths, database plans, or other information on your web service.

display_startup_errors = Off
; Whether to display PHP startup errors.
; Even if the display_errors directive is turned on, turning this parameter off will not display errors when PHP starts.
; It is recommended that you turn off this feature unless you must use it for debugging.

report_memleaks = On
; Whether to report memory leaks. This parameter only works in PHP compiled in debug mode,
; and must include E_WARNING in the error_reporting directive

report_zend_debug = On
; No documentation yet

html_errors = On
; Whether to use HTML tags in error messages.
; Note: Do not use this feature on published sites!

docref_root = ;"http://localhost/phpmanual/"
docref_ext = ;".html"
; If the html_errors directive is turned on, PHP will display a hyperlink on the error message.
; Direct link to a page describing the error or the function that caused the error.
; You can download the php manual from http://www.php.net/docs.php,
; and point the docref_root directive to the URL directory where your local manual is located.
; You must also set the docref_ext directive to specify the file extension (must contain '.').
; Note: Do not use this feature on published sites.

error_prepend_string = ;""
; String used to output before error message
error_append_string = ;""
; Used String output after the error message

xmlrpc_errors = Off
xmlrpc_error_number = 0
; No documentation yet


[PHP-Core-Logging]

define_syslog_variables = Off
; Whether to define various system log variables, such as: $LOG_PID, $LOG_CRON, etc.
; Good idea to turn it off to be more efficient.
; You can call define_syslog_variables() function to define these variables at runtime.

error_log =
; Which file to record the error log to. The file must be writable by the web server user.
; syslog means logging to the system log (event log under NT, syslog(3) under Unix)
; If no value is set here, the error will be logged to the error log of the web server .

log_errors = Off
; Whether to record errors in the log file and where to record them depends on the error_log directive.
; It is strongly recommended that you use logging errors instead of direct output when you finally publish the web site.
; This will let you know what went wrong without exposing sensitive information.

log_errors_max_len = 1024
; Set the maximum length of the error source associated with the error message attached to the error log.
; The value set here is valid for displayed and logged errors as well as $php_errormsg.
; Set to 0 to allow unlimited length.

ignore_repeated_errors = Off
; Whether to ignore repeated error messages when recording error logs.
; Error messages must appear on the same line in the same file to be considered duplicates.

ignore_repeated_source = Off
; Whether to ignore repeated error sources when ignoring repeated error messages.


[PHP-Core-Mail]
; For the mail function to be available, PHP must have access to the sendmail program at compile time.
; If using other mail programs, such as qmail or postfix, make sure to use the corresponding sendmail wrapper.
; PHP will first search for sendmail in the system's PATH environment variable, and then search in the following order:
; /usr/bin:/usr/sbin:/usr/etc:/etc:/usr/ucblib: /usr/lib
; It is strongly recommended that sendmail can be found in PATH.
; In addition, the user compiling PHP must have access to the sendmail program.

SMTP = "localhost"
; The host name or IP address of the SMTP server used to send emails in the mail() function. Only for win32.

smtp_port = 25
; The port number of the SMTP server. Only for win32.

sendmail_from =
; The email address in the "From:" header used when sending emails. Only for win32
; This option also sets the "Return-Path:" header.

sendmail_path = "-t -i"
; Only for unix, parameters can also be supported (the default is 'sendmail -t -i')
; The path of the sendmail program, usually "/usr/sbin/sendmail or /usr/lib/sendmail".
; The configure script will try to find the program and set it as the default, but if it fails, you can set it here.
; Systems that do not use sendmail should set this command as a sendmail alternative (if available).
; For example, Qmail users can usually set it to "/var/qmail/bin/sendmail" or "/var/qmail/bin/qmail-inject".
; qmail-inject does not require any options to process mail correctly.

mail.force_extra_parameters =
; Mandatory additional parameter values ​​passed to the sendmail library as additional parameters.
; These parameters will always replace the 5th parameter of mail(), even in safe mode.


[PHP-Core-ResourceLimit]

default_socket_timeout = 60
; Default socket timeout (seconds)

max_execution_time = 30
; each The maximum allowed execution time of the script (seconds), 0 means no limit.
; This parameter helps prevent inferior scripts from endlessly occupying server resources.
; This command only affects the running time of the script itself. Any other time spent outside the running of the script, such as the use of system()/sleep() functions, database queries, file uploads, etc., will Not included.
; In safe mode, you cannot use ini_set() to change this setting at runtime.

memory_limit = 128M
; The maximum number of memory bytes that a script can apply for (K and M can be used as units).
; This helps prevent bad scripts from consuming all the memory on the server.
; To be able to use this directive, you must use the "--enable-memory-limit" configuration option when compiling.
; If you want to remove the memory limit, you must set it to -1 .
; After setting this directive, the memory_get_usage() function will become available.

max_input_time = -1
; The maximum allowed time (seconds) for each script to parse input data (POST, GET, upload).
; -1 means no limit.

max_input_nesting_level = 64
; The maximum nesting depth of input variables (no more explanation documentation yet)

post_max_size = 8M
; The maximum byte length of POST data allowed. This setting also affects file uploads.
; If the POST data exceeds the limit, $_POST and $_FILES will be empty.
; To upload large files, this value must be greater than the value of the upload_max_filesize directive.
; If memory limit is enabled, this value should be smaller than the value of the memory_limit directive.

realpath_cache_size = 16K
; Specifies the realpath (normalized absolute path name) buffer size used by PHP.
; This value should be increased to improve performance on systems where PHP opens a large number of files.

realpath_cache_ttl = 120
; Validity period (seconds) of the information in the realpath buffer.
; For systems where files rarely change, this value can be increased to improve performance.


[PHP-Core-FileUpLoad]

file_uploads = On
; Whether to allow HTTP file uploads.
; See upload_max_filesize, upload_tmp_dir, post_max_size instructions

upload_max_filesize = 2M
; The maximum size of files allowed to be uploaded.

upload_tmp_dir =
; The temporary directory where files are stored when uploading files (must be a directory writable by the PHP process user).
; If not specified, PHP uses the system default temporary directory.


[PHP-Core-MagicQuotes]
; PHP6 has deleted the following instructions, which is equivalent to all being Off

magic_quotes_gpc = Off
; Whether to input GET/ POST/Cookie data uses automatic string escaping ( ' " NULL ).
; The settings here will automatically affect the value of the $_GEST $_POST $_COOKIE array.
; If this command is turned on at the same time as the magic_quotes_sybase command, Then only the single quote (') will be escaped to (''),
; other special characters will not be escaped, that is, ( " NULL ) will remain intact! !
; It is recommended to turn off this feature and use a custom filter function.

magic_quotes_runtime = Off
; Whether to use automatic string escaping ( ' " NULL ) for data generated from external resources at runtime.
; If this directive is turned on, most functions will be Data returned by resources (databases, text files, etc.) will be escaped.
; For example: data obtained by SQL query, data obtained by exec() function, etc.
; If this command is used with magic_quotes_sybase. If the directive is turned on at the same time, only the single quote (') will be escaped to (''),
; other special characters will not be escaped, that is, ( " NULL ) will remain intact! !
; It is recommended to turn off this feature and use a custom filter function depending on the situation.

magic_quotes_sybase = Off
; Whether to use Sybase-style automatic string escaping (represented by '')


[PHP-Core-HighLight]

highlight.bg = "#FFFFFF"
highlight.comment = "#FF8000"
highlight.default = "#0000BB"
highlight.html = "#000000"

; Anything that is accepted by will work fine.


[PHP-Core-Langue]

short_open_tag = On
; Whether to allow the use of "" short tag. Otherwise the "" long identifier must be used.
; Please do not use short tags unless your php program is run in a controlled environment and for your own use only.
; If you want to use PHP with XML, you can choose to turn off this option to facilitate direct embedding of "",
; Otherwise you must use PHP to output:
>; This directive also affects the abbreviation "
asp_tags = Off
; Whether to allow the ASP style tag "<% %>", which will also affect the abbreviation "<%=".
; This directive will be deleted in PHP6

arg_separator.output = "&"
; The separator used to separate parameters in the URL generated by PHP.
; You can also use "&" or "," etc.

arg_separator.input = "&"
; A list of separators used by PHP when parsing variables in URLs.
; Each character in the string will be treated as a separator.
; You can also use ",&" and so on.

allow_call_time_pass_reference = On
; Whether to force parameters to be passed by reference when calling functions (you will receive a warning every time you use this feature).
; PHP opposes this approach and has deleted this directive (equivalent to setting it to Off) in PHP6 because it affects the cleanliness of the code.
; It is encouraged to explicitly specify in the function declaration which parameters are passed by reference.
; We encourage you to turn this option off to ensure that your scripts will still work properly in future versions of the language.

auto_globals_jit = On
; Whether to create it only when the $_SERVER and $_ENV variables are used (instead of automatically creating it when the script is started).
; If these two arrays are not used in the script, turning on this directive will improve performance.
; For this directive to take effect, the register_globals and register_long_arrays directives must be turned off.

auto_prepend_file =
auto_append_file =
; Specifies the file name to be automatically parsed before/after the main file. Empty disables this feature.
; The file is included as if the include() function was called, so the value of the include_path directive is used.
; NOTE: If the script is terminated via exit(), the automatic suffix will not occur.

variables_order = "EGPCS"
; PHP registers the order of Environment, GET, POST, Cookie, Server variables.
; Represented by E, G, P, C, S respectively, registered from left to right, the new value overwrites the old value.
; For example, setting to "GP" will cause the POST variable to overwrite the GET variable of the same name,
; and completely ignore the Environment, Cookie, Server variables.
; It is recommended to use "GPC" or "GPCS" and use the getenv() function to access environment variables.

register_globals = Off
; Whether to register E, G, P, C, S variables as global variables.
; Turning this directive on may cause serious security issues unless your scripts are checked very carefully.
; It is recommended to use predefined super global variables: $_ENV, $_GET, $_POST, $_COOKIE, $_SERVER
; This directive is affected by the variables_order directive.
; This directive has been removed in PHP6.

register_argc_argv = On
; Whether to declare $argv and $argc global variables (including information using the GET method).
; It is recommended not to use these two variables and turn off this instruction to improve performance.

register_long_arrays = On
; Whether to enable old-style long arrays (HTTP_*_VARS).
; Encourage the use of short-form predefined superglobal arrays and turn this feature off for better performance.
; This directive has been removed in PHP6.

always_populate_raw_post_data = Off
; Whether to always generate $HTTP_RAW_POST_DATA variable (raw POST data).
; Otherwise, this variable is only generated when data of an unrecognized MIME type is encountered.
; However, a better way to access the raw POST data is php://input .
; $HTTP_RAW_POST_DATA is not available for form data with enctype="multipart/form-data".

unserialize_callback_func =
; If the deserialization processor needs to instantiate an undefined class,
; the callback function specified here will be unserialize() with the name of the undefined class as a parameter Call,
; to avoid getting an incomplete "__PHP_Incomplete_Class" object.
; If no function is specified here, or the specified function does not contain (or implement) the undefined class, a warning message will be displayed.
; So only set this directive if you really need to implement such a callback function.
; To disable this feature, simply leave it blank.

y2k_compliance = On
; Whether to force Y2K compliance to turn on (may cause problems in non-Y2K compliant browsers).

zend.ze1_compatibility_mode = Off
; Whether to use the mode compatible with Zend Engine I (PHP 4.x). This directive will be deleted in PHP6 (equivalent to Off).
; This will affect object copying, construction (objects without attributes will produce FALSE or 0), and comparison.
; In compatibility mode, objects will be passed by value instead of by reference by default.

precision = 14
; The number of significant digits displayed in floating point data.

serialize_precision = 100
; The precision (significant digits) when serializing and storing floating-point and double-precision data.
; The default value ensures that floating point data is decoded by the deserializer without losing data.


[PHP-Core-OutputControl]
; The output control function is useful, especially when sending HTTP headers after the information has been output.
; The output control function will not affect the HTTP headers sent by functions such as header() or setcookie().
; It will only affect the information output by the echo() function and the information embedded between the PHP code. information.

implicit_flush = Off
; Whether to require the PHP output layer to automatically refresh data after each output block.
; This is equivalent to automatically calling the flush() function after each print(), echo(), and HTML block.
; Turning this option on has a serious impact on the performance of program execution and is usually only recommended for debugging.
; In CLI SAPI execution mode, this command defaults to On.

output_buffering = 0
; Output buffer size (bytes). The recommended value is 4096~8192.
; Output buffering allows you to send HTTP headers (including cookies) even after outputting the body content.
; The price is that the output layer slows down a little.
; Setting up output buffering can reduce writes and sometimes the sending of network packets.
; The actual benefit of this parameter depends greatly on what web server you are using and what kind of script.

output_handler =
; Redirects the output of all scripts to an output handler function.
; For example, when redirecting to the mb_output_handler() function, the character encoding will be transparently converted to the specified encoding.
; Once you specify an output handler here, output buffering will be automatically turned on (output_buffering=4096).
; Note 0: Only PHP built-in functions can be used here, custom functions should be specified using ob_start() in the script.
; Note 1: Portable scripts must not rely on this directive, but should use the ob_start() function to explicitly specify the output processing function.
; Using this command may cause errors in scripts you are not familiar with.
; Note 2: You cannot use the two output processing functions "mb_output_handler" and "ob_iconv_handler" at the same time.
; You cannot use the "ob_gzhandler" output processing function and the zlib.output_compression directive at the same time.
; Note 3: If you use the zlib.output_handler directive to enable zlib output compression, this directive must be empty.


[PHP-Core-Directory]

include_path = ".:/path/to/php/pear"
; Specify a set of directories for require(), The include(), fopen_with_path() functions find files.
; The format is similar to the system's PATH environment variable (separated by colons under UNIX and semicolons under Windows):
; UNIX: "/path1:/path2"
; Windows: "path1;path2 "
; Use '.' in the include path to allow relative paths, which represent the current directory.

user_dir =
; Tell PHP which directory to look for when using /~username to open the script. It is only valid when it is not empty.
; That is, use the basic directory name of the PHP file under the user directory, for example: "public_html"

extension_dir = "/path/to/php"
; Store extension libraries (modules) directory, which is the directory used by PHP to find dynamic extension modules.
; The default under Windows is "C:/php5"


[PHP-Core-HTTP]

default_mimetype = "text/html"
default_charset = ;" gb2312"
; PHP will automatically output the "Content-Type: text/html" HTTP header by default.
; If the default_charset directive is set to "gb2312",
; then "Content-Type: text/html; charset=gb2312" will be automatically output.
; PHP6 opposes the use of the default_charset directive and recommends the use of the unicode.output_encoding directive.


[PHP-Core-Unicode]
; PHP6 provides comprehensive Unicode support based on the ICU (International Components for Unicode) library.
; You need to use --with-icu-dir= when compiling to specify the installation location of the ICU header files and libraries.
; Except detect_unicode, all others are new instructions in PHP6.

; There is currently a lack of information on PHP6, so the content in this section may be incomplete or even incorrect.

detect_unicode = On
; Indicates whether the Zend engine detects whether a script contains multi-byte characters by checking the script's BOM (Byte Order Mark).
; It is recommended to close. PHP6 has canceled this directive and replaced its function with the unicode.script_encoding directive.

unicode.semantics = Off
; Whether to enable Unicode support.
; If this directive is turned on, PHP will become a complete Unicode environment, such as:
; All strings and variables accepted from HTTP will become Unicode, and all PHP identifiers can also use Unicode character.
; Moreover, PHP will use Unicode strings internally and be responsible for automatic conversion of peripheral non-Unicode characters,
; For example: HTTP input and output, streams, file system operations, etc., even php.ini itself will Parsed according to UTF-8 encoding.
; After enabling this command, you must explicitly specify the binary string. PHP will make no assumptions about the contents of binary strings,
; so your program must ensure that it handles binary strings appropriately.
; If you turn this directive off, PHP will behave exactly as before:
; Strings will not become Unicode, file and binary strings will be backwards compatible, and php.ini will follow " as-is" style parsing.
; Regardless of whether this directive is turned on or not, all functions and operators transparently support Unicode strings.

unicode.fallback_encoding = UTF-8
; Sets the default value for all other unicode.*_encoding directives.
; That is to say, if a unicode.*_encoding directive is not explicitly set, the value set here will be used.

unicode.runtime_encoding =
; The runtime encoding specifies the encoding used when converting binary strings internally within the PHP engine.
; The settings here have no effect on I/O related operations (such as: writing to standard output/reading the file system/decoding HTTP input variables).
; PHP also allows you to convert strings explicitly:
; (binary)$str -- Convert to binary string
; (unicode)$str -- Convert to Unicode string
; (string)$str -- Convert to Unicode string if unicode.semantics is On, otherwise convert to binary string
; For example, if the value of this directive is iso-8859-1 and $uni is a Unicode string, then
; $str = (binary)$uni
; will wait for a binary string encoded using iso-8859-1.
; PHP will implicitly convert the relevant strings to Unicode before operations such as connection, comparison, and parameter passing, and then perform operations.
; For example, when concatenating a binary string with Unicode,
; PHP will use the settings here to convert the binary string into a Unicode string before performing the operation.

unicode.output_encoding =
; The encoding used by PHP to output non-binary strings.
; Automatically convert output content such as 'print' and 'echo' to the encoding set here (without converting binary strings).
; When writing data to an external resource such as a file,
; you must rely on the stream encoding feature or manually encode the data using Unicode extended functions.
; In PHP6, the use of the previous default_charset directive is deprecated and the use of this directive is recommended.
; The previous default_charset directive only specified the character set in the Content-Type header and did not perform any conversion on the actual output.
; In PHP6, the default_charset directive is only effective when unicode.semantics is off.
; After setting this directive, the value of this directive will be filled in the 'charset' part of the Content-Type output header,
; regardless of how the default_charset directive is set.

unicode.http_input_encoding =
; The encoding of the content of variables obtained via HTTP (such as $_GET and _$POST).
; This feature was still under development until April 2007....

unicode.filesystem_encoding =
; The encoding of the directory name and file name of the file system.
; File system related functions (such as opendir()) will use this encoding to accept and return file names and directory names.
; The setting here must be exactly the same as the encoding actually used by the file system.

unicode.script_encoding =
; The default encoding of the PHP script itself.
; You can use any encoding supported by ICU to write PHP scripts.
; If you want to set the encoding for a separate script file, you can use
; at the beginning of the script;
; to specify. Note: It must start at the beginning of the first line and should not contain any characters (including spaces).
; This method can only affect the script in which it is located, and will not affect any other included scripts.

; Whether to let PHP automatically detect end-of-line characters (EOL).
; If your script must process Macintosh files,
; or if you are running on a Macintosh and also need to process unix or win32 files,
; turning on this command will allow PHP to automatically detect EOL for fgets () and file() functions work fine.
; But it will also cause incompatible behavior for people who use the carriage return (CR) as the project separator under Unix systems.
; Additionally, there is a small performance penalty when detecting the EOL habit of the first row.

doc_root =
; PHP's "CGI root directory". Only valid when non-empty.
; It is considered unsafe to place executable programs/scripts in the main document directory of a web server (such as "htdocs")
; For example, due to misconfiguration, the script will be displayed as ordinary html.
; Therefore, many system administrators will set up a directory outside the main document directory that can only be accessed through CGI.
; The content in this directory will only be parsed and will not be displayed as it is.
; If this option is set, PHP will only interpret files in the doc_root directory,
; and ensure that scripts outside the directory will not be executed by the PHP interpreter (except user_dir).
; If PHP is compiled without specifying FORCE_REDIRECT and is run as CGI on a non-IIS server,
; this directive must be set (see the Security section in the manual).
; The alternative is to use the cgi.force_redirect directive.

cgi.fix_pathinfo = On
; Whether to provide real PATH_INFO/PATH_TRANSLATED support for CGI ( Comply with cgi specifications).
; The previous behavior was to set PATH_TRANSLATED to SCRIPT_FILENAME regardless of PATH_INFO.
; Turning this option on will cause PHP to correct its paths to comply with the CGI specification, otherwise the old non-conforming behavior will still be used.
; You are encouraged to turn this directive on and fix your script to use SCRIPT_FILENAME instead of PATH_TRANSLATED.
; See the cgi specification for more information on PATH_INFO.

cgi.force_redirect = On
; Whether to turn on cgi force redirection. It is highly recommended to turn it on to provide security for PHP running in CGI mode.

cgi.rfc2616_headers = 0
; Specifies what headers PHP uses when sending HTTP response codes.

; The maximum recursion depth of PCRE.
; If you set this value very high, it may exhaust the process's stack space and cause PHP to crash.


[Session]
; Unless a variable is registered using session_register() or $_SESSION.
; Otherwise, no session records will be automatically added regardless of whether session_start() is used or not.
; Objects that include resource variables or have circular references. Objects that contain references to themselves cannot be saved in the session.
; The register_globals directive affects the storage and recovery of session variables.

session.save_handler = "files"
; Name of the handler that stores and retrieves data associated with the session. Defaults to files ("files").
; If you want to use a custom processor (such as a database-based processor), use "user".
; Set to "memcache" to use memcache as the session processor (you need to specify the "--enable-memcache-session" compilation option).
; There is also a processor using PostgreSQL: http://sourceforge.net/projects/phpform-ext/

session.save_path = "/tmp"
; Passed to the storage processor parameters. For the files processor, this value is the path to the session data file where the session data file was created.
; The default is the temporary folder path under Windows.
; You can use the pattern "N;[MODE;]/path" to define the path (N is an integer).
; N means using N-level subdirectories instead of saving all data files in one directory.
; [MODE;] Optional, must use octal number, the default is "600", indicating the file access permission.
; This is a good idea to improve performance for a large number of sessions.
; Note 0: The double quotes around "N;[MODE;]/path" cannot be omitted.
; Note 1: [MODE;] does not rewrite the umask of the process.
; Note 2: PHP will not automatically create these folder structures. Please use the mod_files.sh script in the ext/session directory to create it.
; Note 3: If the folder can be accessed by insecure users (such as the default "/tmp"), it will cause security vulnerabilities.
; Note 4: Automatic garbage collection will fail when N>0. For details, see the section on garbage collection below.
; [Security Tips] It is recommended to set up different directories for each different virtual host.

; For the "memcache" handler, you need to define a comma-separated server URL to store session data.
; For example: "tcp://host1:11211, tcp://host2:11211"
; Each URL can contain parameters passed to that server. The available parameters are the same as Memcache::addServer() The method is the same.
; For example: "tcp://host1:11211?persistent=1&weight=1&timeout=1&retry_interval=15"

session.name = "PHPSESSID"
;The session ID used in the cookie The first name can only contain letters and numbers.

session.auto_start = Off

; Because class definitions must be loaded before the session is started, you cannot store objects in the session if this option is turned on.

session.serialize_handler = "php"
; Processor used to serialize/deserialize data. PHP is a standard serialization/deserialization processor.
; You can also use "php_binary". When WDDX support is enabled, only "wddx" can be used.

session.gc_probability = 1
session.gc_divisor = 100
; Defines the probability of starting the garbage collection program every time the session is initialized.
; The calculation formula for this collection probability is as follows: session.gc_probability/session.gc_divisor
; The more frequently the session page is accessed, the smaller the probability should be. The recommended value is 1/1000~5000.

session.gc_maxlifetime = 1440
; After the number of seconds indicated by this parameter, the saved data will be considered 'garbage' and cleaned by the garbage collector.
; The judgment criterion is the time when the data was last accessed (for the FAT file system, it is the time when the data was last refreshed).
; If multiple scripts share the same session.save_path directory but have different session.gc_maxlifetimes,
; then the minimum value among all session.gc_maxlifetime directives will prevail.
; If multiple levels of subdirectories are used to store data files, the garbage collection process will not start automatically.
; You must use a shell script, cron entry, or other method written by yourself to perform garbage collection.
; For example, the following script is equivalent to setting "session.gc_maxlifetime=1440" (24 minutes):
; cd /path/to/sessions; find -cmin +24 | xargs rm

session.referer_check =
; If the "Referer" field in the request header does not contain the string specified here, the session ID will be considered invalid.

apc.file_update_protection = 2
; When you modify files on a running server, you should perform atomic operations.
; That is, first write to a temporary file, and then rename (mv) the file to the final name.
; Text editors and programs such as cp and tar do not operate this way, resulting in the possibility of buffering incomplete files.
; The default value 2 means that when accessing a file, if the modification time is found to be less than 2 seconds from the access time, no buffering will be performed.
; The unlucky visitor may get corrupted content, but the bad effect is not magnified by caching.
; If you can ensure that all update operations are atomic, you can turn off this feature with 0.
; If your system updates slowly due to heavy IO operations, you may need to increase this value.

apc.user_ttl = 0
; Similar to apc.ttl, but for each user, the recommended value is 7200~86400.
; Setting to 0 means that the buffer may fill up with old cache entries, preventing new entries from being cached.

apc.gc_ttl = 3600
; The number of seconds that cache entries can exist in the garbage collection table.
; This value provides a safety measure, even if a server process crashes while executing a cached source file,

apc.mmap_file_mask =
; If APC was compiled with MMAP support using --enable-mmap (enabled by default),
; The value here is the mktemp-style file mask passed to the mmap module code (the recommended value is "/tmp/apc.XXXXXX").
; This mask is used to determine whether the memory mapped area should be file-backed or shared memory backed.
; For direct file-backed memory mapping, set it to "/tmp/apc.XXXXXX" (exactly 6 X's).
; To use POSIX-style shm_open/mmap, you need to set it to "/apc.shm.XXXXXX".

; If set to an integer, it represents the corresponding Unicode value. Not setting any value means not to display this error character.
; It is recommended to set it to "□"


[Mcrypt]
; An interface to the mcrypt library, which supports many block encryption algorithms.
; It is not recommended to use this module because there are too many problems. It is recommended to encrypt at the database layer.

[Memcache-2.2.2]
; A high-performance distributed memory object cache system that maintains a unified huge hash table in memory,
; It can be used to store data in various formats, including images, videos, files, and database search results.

memcache.allow_failover = On
; Whether to transparently fail over to other servers when an error is encountered.

memcache.chunk_size = 8192
; Data will be transferred according to the block size set by this value. Smaller values ​​require more additional network traffic.
; If you notice unexplained slowdowns, you can try increasing this value to 32768.

memcache.default_port = 11211
; The default TCP port used when connecting to the memcached server.

memcache.max_failover_attempts = 20
; The maximum number of servers to try when receiving and sending data, effective when memcache.allow_failover is turned on.

memcache.hash_strategy = "standard"
; Controls the strategy for mapping keys to servers. The default value "standard" means to use the old hash strategy of the previous version.
; Set to "consistent" to allow adding/removing servers from the connection pool without having to recalculate the mapping between key and server.

memcache.hash_function = "crc32"
; Controls the hash function that maps keys to the server. The default value "crc32" uses the CRC32 algorithm, while "fnv" means the FNV-1a algorithm is used.
; FNV-1a is slightly slower than CRC32, but has better hashing results.


[Zlib]
; This module allows PHP to transparently read and write gzip (.gz) compressed files.

zlib.output_compression = Off
; Whether to use the zlib library to transparently compress script output results.
; The value of this command can be set to: Off, On, number of bytes (compression buffer size, default is 4096).
; If this directive is turned on, when the browser sends the "Accept-Encoding: gzip(deflate)" header,
; the "Content-Encoding: gzip(deflate)" and "Vary: Accept-Encoding" headers will Added to the response header.
; You can enable or disable this feature in a script using the ini_set() function before response headers are output.
; If a "Content-Type: image/??" response header is output, compression will not be enabled (to prevent Netscape bugs).
; You can use "ini_set('zlib.output_compression', 'On')" to re-enable this feature after outputting "Content-Type: image/??".
; Note 1: The compression rate will be affected by the size of the compression buffer. If you want better compression quality, please specify a larger compression buffer.
; Note 2: If zlib output compression is enabled, the output_handler directive must be empty, and the value of the zlib.output_handler directive must be set.

zlib.output_compression_level = -1
; Compression level, available values ​​are 0~9, 0 means no compression. The higher the value, the better the effect, but the more CPU usage. The recommended value is 1~5.
; The default value -1 means to use the zlib internal default value (6).

zlib.output_handler =
; With the zlib.output_compression directive turned on, you can only specify the output processor here.
; The processors that can be used are "zlib.inflate" (decompression) or "zlib.deflate" (compression).
; If this directive is enabled, the output_handler directive must be set to empty.


[dbx]
; A database abstraction layer that provides a unified interface for different databases. Currently supported:
; FrontBase, SQL Server, MySQL, ODBC, PostgreSQL, Sybase-CT, Oracle 8, SQLite

dbx.colnames_case = "unchanged"
; Field names can be as "unchanged" Or return in "uppercase", "lowercase" mode.

; The MySQLi module can only work with MySQL versions 4.1.3 and above.

mysqli.max_links = -1
; The maximum number of connections allowed per process (persistent and non-persistent).-1 represents unlimited

mysqli.default_port = 3306
; The default TCP port used by mysqli_connect() to connect to the MySQL database.
; If no default value is specified here, it will be searched in the following order:
; (1) $MYSQL_TCP_PORT environment variable
; (2) mysql-tcp item (unix) in the /etc/services file
; (3) The MYSQL_PORT constant specified during compilation
; Note: Under Win32, only the MYSQL_PORT constant is used.

; The default username used by mysqli_connect() to connect to the MySQL database. Not valid in safe mode.

mysqli.default_pw =
; The default password used by mysqli_connect() to connect to the MySQL database. Not valid in safe mode.
; Saving passwords in configuration files is a bad idea, anyone with PHP rights can run
; 'echo cfg_get_var("mysql.default_password")' to display the password!
