Where does PHP store the error log? (PHP 5, Apache, FastCGI, and cPanel)

I am on shared hosting and have [cPanel][1], Apache, and PHP is run by [FastCGI][2]. Where does PHP store the error log? Is there another way I can find the error log on a shared hosting environment instead of having to go through entire site structure to look for *error_log* files? I have access to the *php.ini* file (I am using PHP version 5.2.16). [1]: https://en.wikipedia.org/wiki/CPanel [2]: https://en.wikipedia.org/wiki/FastCGI
