If I send data in a $_REQUEST['var'] like if (isset($_REQUEST['var'])) { } Put var has no data it still says it is set. Because $_REQUEST['var'] = "" and isset thinks "" is setI use this combination a lot: if ( isset($_GET['something']) && !empty($_GET['something']) ) {// do something here with $_GET['something']}
