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']
}

Different eyes see different things. Different hearts beat on different strings. But there are times
for you and me when all such things agree.
