Well it depends on the Linux distribution you are using, the version of php and the way you install it with Apache web server. Php.ini may be here:
/etc/php.ini
Or here:
/etc/php/php.ini
/etc/php5/php.ini
Or here:
/usr/bin/php5/bin/php.ini
Anyway, you can always find any file named php.ini in this manner
find / -name php.ini
The simplest yet most powerful usage of the renowned find command. By its help I was able to locate the php.ini on my Ubuntu 9.04 Apache2 and PHP5:
/etc/php5/apache2/php.ini
Use phpinfo() to find out
Write a simple PHP file with the following content:
<?php phpinfo();
And upload it to your server and access it in your web browser to get a page like this:
