[PHP]
; PHP is still an evolving tool, and its functions are still being deleted
; And the setting changes in php.ini can reflect considerable changes,
; When using the new PHP Before versioning, it would be beneficial to study php.ini
;;;;;;;;;;;;;;;;;;;;
; About this file ;
; This file controls many aspects of PHP. In order for PHP to read this file, it must be named
; 'php.ini'. PHP will search for the file in these places: the current working directory; the path specified by the environment variable PHPRC
;; the path specified during compilation.
; Under Windows, the path when compiling is the Windows installation directory.
; In command line mode, the search path of php.ini can be replaced with the -c parameter.
; The syntax of this file is very simple. Whitespace characters and lines starting with a semicolon ';' are simply ignored (as you might have guessed
; ). Section titles (eg: [Foo]) are also simply ignored, even though they may
; have some meaning in the future.
; Directives are specified using the following syntax:
; directive = value
; directive = value
; directive is *case-sensitive* - foo=bar is different from FOO = bar.
; The value can be a string, a number, a PHP constant (such as: E_ALL or M_PI), an INI constant
; a (On, Off, True, False, Yes, No and None), or an expression
; (such as: E_ALL & ~E_NOTICE), or a string enclosed in quotes ("foo").
; INI file expressions are restricted Bitwise operators and parentheses. boolean NOT
status.
; They can be set to off using the values 0, Off, False or No.
; An empty string can be represented by not writing anything 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 constants in value settings, and these constants are dynamic Called into the extension library (either PHP extension, or
; Zend extension), you can only use these constants *after* the lines that call in these extensions.
; All values set in the php.ini-dist file are the same as the built-in defaults (this means that if php.ini
; is not used or you delete these lines , the default value is the same).
; Language options;
engine = On
; Make the PHP scripting language engine (PHP scripting language engine) valid under Apache.
short_open_tag = On
; Allows tags to be recognized.
asp_tags = Off
; Allow ASP-style tags
precision = 14
; The number of effective digits when displaying floating point type numbers
y2k_compliance = Off
; Whether to turn it on Year 2000 Adaptation (may cause issues in non-Y2K compliant browsers)
output_buffering = Off
; Output buffering allows you to send header (including cookies) lines even after outputting the body content
; The price is that the output layer slows down a little. You can use Output Cache to turn on output caching at runtime,
; or set the directive to On here to turn on output caching for all files.
output_handler = ; You can redirect all output of your script to a function,
; Doing so may be useful for processing or logging it.
; For example, if you set this output_handler to "ob_gzhandler",
; then the output will be transparently compressed for browsers that support gzip or deflate encoding.
; Set an output processor to automatically open output buffering.
implicit_flush = Off
; Force flush (refresh) to let PHP tell the output layer to automatically refresh its own data after each output block.
; This is equivalent to calling the flush() function after every print() or echo() call and after every HTML block.
; Turning on this setting will cause serious runtime conflicts. It is recommended to turn it on only during debugging.
allow_call_time_pass_reference = On
; Whether to force parameters to be passed by reference when calling functions. This method was protested
; and may no longer be supported in future versions of PHP/Zend.
; It is encouraged to specify which parameters are passed by reference in the function declaration.
; You are encouraged to try turning this option off and verify that your scripts still work, to ensure that they will still work in future versions of the language
; (You will get a warning every time you use this feature, and arguments will be passed by value rather than by reference
; ).
; Safe Mode Safe Mode
safe_mode = Off
safe_mode_exec_dir =
safe_mode_allowed_env_vars = PHP_
; ? Setting certain environment variables
; ? may be a potential security breach.
; This directive contains a comma-separated list of prefixes. In safe mode, users can only replace the value of environment variables
; that begin with the prefixes listed here.
; By default, users will only be able to set environment variables starting with PHP_ (eg: PHP_FOO=BAR).
; Note: If this directive is empty, PHP will let the user change any environment variables!
safe_mode_protected_env_vars = LD_LIBRARY_PATH
; This directive contains a comma-separated list of environment variables that are End users will not be able to change it using putenv().
; These variables are protected even when safe_mode_allowed_env_vars is set to allowed.
disable_functions =
; This directive allows you to disable specific functions for security reasons.
; It accepts a comma separated list of function names.
; This instruction *is not* affected by whether safe mode is turned on.
; The color of syntax highlighting mode.
; As long as it is acceptable, it will work.
highlight.string = #DD0000
highlight.comment = #FF8000
highlight.keyword = #007700
highlight.bg = #FFFFFF
highlight.default = #0000BB
highlight.html = #000000
; Misc Miscellaneous
expose_php = Off
; Determines whether PHP should indicate the fact that it is installed on the server (e.g. add it -PHP- to the web service
; on the signal sent).
; (My personal opinion is to turn this off when any power-by header appears.)
; It does not pose a security threat, but it allows you to check whether it is installed on your server. Made possible with PHP.
; Resource Limits ;
max_execution_time = 30 ; The maximum execution time of each script, in seconds
memory_limit = 8388608 ; The maximum execution time of a script The total amount of memory available (here is 8MB)
; Error handling and logging;
; Error control and registration;
; Error reporting is bitwise of. Or add up the numbers to get the desired error reporting level.
; E_ALL - all errors and warnings
; E_ERROR - fatal runtime errors
; E_WARNING - runtime warnings (non-fatal errors)
; E_PARSE - compile-time parsing errors
; E_NOTICE - Runtime reminders (these are often caused by bugs in your code,
; may also be caused by intentional behavior.(For example: using an uninitialized variable based on the fact that the uninitialized variable is automatically initialized to an
; empty string)
; E_CORE_ERROR - a fatal error that occurs during the initialization process when PHP starts up
; E_CORE_WARNING - a warning that occurs during the initialization process of PHP (non-fatal error)
; E_COMPILE_ERROR - a compile-time fatal error
; ; E_USER_ERROR - User-generated error message
; E_USER_WARNING - User-generated warning message
; E_USER_NOTICE - User-generated reminder message
; Example:
; error_reporting = E_ALL & ~E_NOTICE ; Show all Errors, except reminders
; error_reporting = E_COMPILE_ERROR|E_ERROR|E_CORE_ERROR ; Display errors only
error_reporting = E_ALL & ~E_NOTICE ; Display all errors, except reminders
display_errors = On ; Display error messages (as output) part)
; On the final published web site, it is strongly recommended that you turn off this feature and use the
; error log instead (see below).
; Continuing to enable display_errors on the final published web site may
; expose some security-related information, such as file paths on your web service,
; your database layout, or other information.
display_startup_errors = Off ; Even when display_erroes is turned on, errors that occur during the PHP startup step
; will not be displayed.
; It is strongly recommended to keep display_startup_errors turned off,
; except during error correction.
log_errors = Off; Record errors in a log file (server-specified log, stderr standard error output, or error_log (below))
; As explained above, it is strongly recommended that you publish it on the final web site Log errors
; instead of direct error output.
track_errors = Off ; Save the latest error/warning message in the variable $php_errormsg (boolean)
;error_prepend_string = "" ; The string output before the error message
;error_append_string = "" ; The string output after the error message
;error_log = filename ; Record the error log in the specified file
;error_log = syslog ; Record the error log in the system log syslog (event log under NT, invalid under Windows 95)
warn_plus_overloading = Off ; Warn when using '+' for strings
; Data Handling ;
variables_order = "EGPCS" ; This directive describes PHP records
; the order of GET, POST, Cookie, Environment and Built-in variables.
; (represented by G, P, C, E & S, usually cited as EGPCS or GPC).
; Record from left to right, with new values replacing old values.
register_globals = On ; Whether to register these EGPCS variables as global variables.
; You may want to turn this off if you don't want user data to be cluttered globally.
; This makes more sense in conjunction with track_vars - so you can access all GPC variables via the
; $HTTP_*_VARS[] array.
register_argc_argv = On; This instruction tells PHP whether to declare argv and argc variables
; (Note: here argv is an array and argc is the number of variables)
; (which includes the GET method) data).
; If you don’t want to use these variables, you should turn them off to improve performance.
track_vars = On ; Make the $HTTP_*_VARS[] array valid, where * is replaced with
; ENV, POST, GET, COOKIE or SERVER when used.
post_max_size = 8M; PHP will accept The maximum size of POST data.
gpc_order = "GPC" ; This instruction was objected. Use variables_order instead.
; Magic quotes
magic_quotes_gpc = On ; Use magic quotes in the input GET/POST/Cookie data
; (The original text is like this, haha, the so-called magic quotes should refer to the use of escape characters Added to reference control characters, such as '....)
magic_quotes_runtime= Off; Use magic references for data generated during runtime,
; For example: use exec() to query data obtained by SQL Data obtained by functions, etc.
magic_quotes_sybase = Off ; Use Sybase style magic quotes (use '' out ' instead of ' )
; Automatically add files before and after PHP documents
auto_prepend_file =
auto_append_file =
; Like 4.04b4, PHP always outputs the encoding of a character in the "Content-type:" header by default.
