Re: When is $_POST set and unset?

Posted by Steve Belanger on 05/23/07 13:25

all super globals by default are being set to empty, like $_GET, $_POST,
$_COOKIE and so on.

you might want to use empty($_POST) instead. If that check ends up being
true, that means no POST data has been provided. False would mean you sent
data through $_POST.

hope this helps.
