How do I check for the presence of an optional $_GET param without throwing a "Notice: Undefined index" when the param is not present? Tried all three of these, they all produce the Notice when the param is not passed: if ($_GET['id']) if ($_GET['id'] != "") if (isset $_GET['id'])if (@$_GET['id']) http://www.php.net/manual/en/language.operators.errorcontrol.php
