Is there a way to disable PHP from outputting warnings?
error_reporting(E_ALL ^ E_WARNING); (iirc)
This may be helpful too (http://us2.php.net/manual/en/function.error-reporting.php)
Or, if you don't care about ANY verbose:
error_reporting(E_NONE);
Sorry to bump this post, but it may be helpful to note that if you only want to disable warning or error reporting for a single function call, prefix the call with an @.
Ex: @setcookie
