fyi:
you *cannot* do assignments inside of the isset() function. although you *can* while inside of other
functions such as is_null().
<?php
if (isset($var = $_GET['key'])) echo 'whatever'; //this will throw an error :(
if (is_null($var = $_GET['key'])) echo 'whatever'; //this will not :)
?>
hope someone finds this useful.
