a simple clarification about $_SESSION

[Joseph S.]

If I define
$_SESSION['x']=5;

and later, use $x say, as,

$y = $x * $x;

will it work only if register_global s is set to On?

Am i correct in saying that usage of $x in place of $_SESSION['x'] will
not work if register_global s is Off?

TIA,
Regards,
Joseph S.

You are.

Of course, you could just add this line to your code:

$x = $_SESSION['x'];

and then you can use $x in place of $_SESSION['x'].
