what troubled me this time around is cookies......i understood its meaning n what does it do.....
but this line:
is making me confused....as far as i knw the isset function is used to check wether the form is submitted or not...now then y is ($msg) is in parenthesis...wat does this line actually mean??will it check wether $msg value is submitted or not,or what will it do???i have not given any button or submit values $msg in the below code....kindly tell me what does this line actually does...
$msg = '<p>Your settings have been entered...click <a href="view.php">HERE</a>to
see them in action.</p>';
