note 23660 added to function.ctype-alnum

Actually, ctype_alnum ($text) is not equivalent to (ctype_alpha($text) || ctype_digit($text)). For $text="ab12", ctype_alnum returns true, while the second construction returns false (it returns true only when *all* the characters are either letters or digits). -- http://www.php.net/manual/en/function.ctype-alnum.php http://master.php.net/manage/user-notes.php?action=edit+23660 http://master.php.net/manage/user-notes.php?action=delete+23660 http://master.php.net/manage/user-notes.php?action=reject+23660
