Troubleshoot PHP Warnings

If you're seeing PHP warnings or notices in your page out put like this:

<b>Notice</b>:  Undefined variable: params in <b>/var/www/deki-hayes/skins/ace/Ace.php</b> on line <b>690</b>

You will want to change PHP's error_reporting variable so it doesn't display E_NOTICE messages.  E_NOTICE messages display suggestions for optimal PHP coding and are primarly intended for development purposes.  Disabling these can be done in one of two ways:

1) Prefered method:  edit your php.ini file and set this

error_reporting  =  E_ALL & ~E_NOTICE

The restart apache so the change takes effect

2) Alternatively, you can put the following at the beginning of your LocalSettings.php file:

error_reporting(E_ALL & ~E_NOTICE);
