What do you do when isset does not work? 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 $_REQUEST['var'] = "" and isset thinks "" is set
I use this combination a lot: if ( isset($_GET['something']) && !empty($_GET['something']) ) {
    // do something here with $_GET['something']
}
The isset is a pointless waste of cycles. -Stut
I've been accuse of that too, but what's your solution?
In the above example, if (isset($_GET['something']) && !empty($_GET['something'])) { is the same as... if (!empty($_GET['something'])) { So, in that particular line of code the isset is a pointless waste of cycles. -Stut these two lines are not the same infact, with the first, you will not get a E_NOTICE warning, but with the second you will.
