What do you do when isset does not work? If I send data in a

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.

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.
