I've been using empty() for about 5 years, obeying the rules for empty() in the php manual
"Appendix P. PHP type comparison tables" and have never seen it generate any type of error message.
If you guys know of at least one exception, please clue us in on it.

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.

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.

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.
