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.
