Note Submitter: wes at arasian dot com ---- "yarco" stated that: <?php $string = "test"; isset($string['aaaaa']); ?> would return true, when it shouldn't. Actually this is CORRECT behavior, because realize that 'aaaaa' evaluates as 0 numerically, and $string[0] is, indeed, set. To find whether a string exists within a string, use strpos() instead.
