How to check where Apache is looking for a php.ini file?

Question

I have a feeling that Apache is using a different php.ini file that the one I am editing. I make a change in my php.ini file, restart Apache, and the change doesn't take affect. So I don't know what to do anymore.

Any ideas?

Update: Found out it's using the right php.ini file...but I still don't know what to do!

Answer 1

To find the file that's being run by PHP, create a phpinfo file (just <?php phpinfo();?>) and look for the 'Configuration File (php.ini) Path' directive.

Answer 2

from the command line, run

php -i |grep "php.ini"  

This will describe the location php is loading its ini file from. You can reconfigure the php.ini location by recompiling php.
