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.

well, as the OP said, he wants to know when the variable has a
value other the "".
So, to check for that you have to do something like this right?
if ( $var != '' ) {}
if ( strlen($var) > 0 ) {}
if ( !empty($var) ) {}
... a number of other ideas come to mind, but
none of them will work, because they will always product a E_NOTICE
warning.
empty() does NOT produce an E_NOTICE if the variable is not set.
That's one of the things it considers as empty.
And why I always do !empty($foo) then check for a value such as (!
empty($foo) && $foo == $bar)
