PHP: Tips of the Day
PHP: Where does PHP store the error log? (php5, apache, fastcgi, cpanel)
PHP stores error logs in /var/log/apache2 if PHP is an apache2 module. Shared hosts are often storing log files in your root directory /log subfolder. But...if you have access to a php.ini file you can do this:
error_log = /var/log/php-scripts.log
According to rinogo's comment: If you're using cPanel, the master log file you're probably looking for is stored (by default) at
/usr/local/apache/logs/error_log
If all else fails you can check the location of the log file using
<?php phpinfo(); ?>
