note 23473 added to function.strpos

Only 0 is false in PHP non-zero is postive so -2 could be a true. Since they can't use zero becuase it is in the range of possible correct positions within a string. So do the type check against false explicity to prevent odd behavior -- http://www.php.net/manual/en/function.strpos.php http://master.php.net/manage/user-notes.php?action=edit+23473 http://master.php.net/manage/user-notes.php?action=delete+23473 http://master.php.net/manage/user-notes.php?action=reject+23473
