How to change the path to php.ini in PHP CLI version

问题

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

By specifying environment variable PHPRC to point to the same php.ini as the one Apache uses worked for me on Ubuntu

export PHPRC=/etc/php5/apache2/php.ini

Or put it in the $HOME/.bashrc to import every time cli is started

I have spent about 3 hours trying to do exactly what your question asks. Couldn't do it. I gave up and copied that php.ini to C:\Windows and changed my ENV variable "PHPRC" to C:\Windows (and in httpd.conf). That way both my CLI php and Apach php e are using the same file. I could not get "php -m" to display the modules I had loaded in my php.ini for the life of me until I made this change...

回答4:

try running the phpinfo() function on both side

Webserver and CLI and find out the exact location of your php.ini file for both side

and maintain those files only

回答5:

I tried and failed with using C:\YourPathto\PHP7\ as my PHPRC Environmental Variable. But it must be set to the full path with filename. I also found that I had to do a full restart for php to pick up the new variable.

1. On Windows, find the path to your php.ini file and modify and run the following command in a command/terminal window:

   setx PHPRC "C:\YourPathto\PHP7\php.ini"

   You should see SUCCESS: Specified value was saved.

2. Then restart your computer (really).

Or edit environmental variables through the regular way, then restart:
