You can change the error_reporting setting in php.ini to not include E_NOTICE. There should be some examples right in the php.ini file.

However, this is unwise.. What you should do is fix your code. For example, instead of:

if ($_REQUEST['language'] != '')

You should write:

if (isset($_REQUEST['language']))

Fixing all E_NOTICE errors will make your code much more robust.
