Configuration file introduction:

The configuration file (php.ini) is read when PHP starts. For the server module version of PHP, it is read only once when the web server starts. For CGI and CLI versions, it is read on every call.

The search path for php.ini is as follows (in order):

The location specified by the SAPI module (PHPIniDir directive in Apache 2, -c command line option in CGI and CLI, NSAPI php_ini parameter in THTTPD, PHP_INI_PATH environment variable in THTTPD).

PHPRC environment variable. Prior to PHP 5.2.0, it was ordered after the registry keys mentioned below.

Since PHP 5.2.0, you can specify different php.ini file locations for different versions of PHP. The location of the registry directory depends on whether your system is 32-bit or 64-bit. When 32-bit PHP runs on a 32-bit system or 64-bit PHP runs on a 64-bit system, use [(HKEY_LOCAL_MACHINE\SOFTWARE\PHP]]. When 32-bit PHP runs on a 64-bit system, then Use [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\PHP]] instead. When the system version is consistent with the PHP version architecture, it will be checked in the following order: [HKEY_LOCAL_MACHINE\SOFTWARE\PHP\x.y.z], [HKEY_LOCAL_MACHINE\SOFTWARE\PHP\x.y] and [HKEY_LOCAL_MACHINE\SOFTWARE\PHP\x], where x, y and z refer to the PHP major version number, minor version number and release batch. For the 32 bit version of PHP running on a 64 bit system, it will Check in the following order: [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6421Node\PHP\x.y.z], [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6421Node\PHP\x.y] and [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6421Node\PHP\x], where x, y and z Refers to the PHP major version number, minor version number and release batch. If there is a key value for IniFilePath in any of these directories, the first value will be used as the location of php.ini (Windows only).

The value of IniFilePath within [HKEY_LOCAL_MACHINE\SOFTWARE\PHP] (Windows registry location).

Current working directory (for CLI).

Web server directory (for SAPI module ) or the directory where PHP is located (other cases under Windows).

Windows directory (C:\windows or C:\winnt), or the location specified by the --with-config-file-path compile-time option.

If php-SAPI.ini exists (SAPI is the current SAPI name in use, so the actual file name is php-cli.ini or php-apache.ini, etc.), it will be used instead of php.ini.SAPI The name can be determined using php_sapi_name().

Note:

The Apache web server will change the directory to the root directory when it starts, which will cause PHP to try to read php.ini in the root directory, if it exists.
