Question

The php that run on the webserver and the CLI version is not using the same php.ini file. If I do a command php --ini, it show this

Configuration File (php.ini) Path: C:\Windows
Loaded Configuration File:         C:\wamp\bin\php\php5.3.8\php.ini
Scan for additional .ini files in: (none)
Additional .ini files parsed:      (none)

while my web version uses the php.ini in C:\wamp\bin\apache\Apache2.2.21\bin\php.ini. This is probably very common for people using wamp.

How do I change the Loaded Configuration File to read from C:\wamp\bin\apache\Apache2.2.21\bin\php.ini so I don’t have to maintain 2 different php.ini versions?

Per http://php.net/configuration.file:

php.ini is searched for in these locations (in order):

• SAPI module specific location (PHPIniDir directive in Apache 2, -c command line option in CGI and CLI, php_ini parameter in NSAPI, PHP_INI_PATH environment variable in THTTPD)
• The PHPRC environment variable. Before PHP 5.2.0, this was checked after the registry key mentioned below.
• As of PHP 5.2.0, the location of the php.ini file can be set for different versions of PHP. The following registry keys are examined in 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 mean the PHP major, minor and release versions. If there is a value for IniFilePath in any of these keys, the first one found will be used as the location of the php.ini (Windows only).
  • [HKEY_LOCAL_MACHINE\SOFTWARE\PHP], value of IniFilePath (Windows only).
• Current working directory (except CLI).
• The web server’s directory (for SAPI modules), or directory of PHP (otherwise in Windows).
• Windows directory (C:\windows or C:\winnt) (for Windows), or –with-config-file-path compile time option.

For CLI, your best bet is probably either to set the $PHPRC environment variable for the account that will be executing scripts, or recompile PHP with a different --with-config-file-path configuration setting.

You can also override the php.ini search dir on a per-execution basis by specifying the -c option when invoking PHP:

> php --help
Usage: php [options] [-f]  [--] [args...]
...
  -c | Look for php.ini file in this directory
