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.
You COULD always use empty() prefixed with an @ to quiet the E_NOTICE,
Stut wouldn't do that... especially not after calling isset() a waste of
cycles. using the @ to suppress warnings/errors still invokes the error
system, and that includes any error handler you've custom hooked.
Maybe Stut just writes bad code ;) ;)
Cheers,
Rob.
I wouldn't say bad code, but I might say exceptionally noisy code :P
