PHP error logging checklist

Here’s a list of things you can check if you aren’t getting anything written to the PHP error log on your server:

• In php.ini, do you have error_reporting set to E_ALL ?
• In php.ini, do you have log_errors enabled?
• In php.ini, do you have track_errors enabled?
• Have you specified a valid file / location for error_log
• Does the user that starts PHP (e.g apache) have relevant permissions and ownership to write to the PHP error_log file ?
• Does your application have an override set in .htaccess or php.ini for any of the above?
• Have you restarted PHP/Apache after making changes for these things to take effect?
• What does php -i | grep error tell you regarding these settings?
