hi i tried 2 things what should be the same however it my testing says different does anyone know why the only thing i do is put it in a variable...
if ($_SESSION[$something] === null)
echo("this is null");
$_SESSION[$something] does not exists so it indeed says: "this is null". now look at this
$theSession = $_SESSION[$something];
if (theSession === null)
echo("this is null");
now it does not say "this is null" while it should be exactly the same right?
