note 23652 added to function.explode

I want to explode a string like "world" into all its characters. The problem is, with 'explode' you need a seperator, which doesn't exist. So, my question is: Is it possible to do this in php, perhaps with another function, and how. -- http://www.php.net/manual/en/function.explode.php http://master.php.net/manage/user-notes.php?action=edit+23652 http://master.php.net/manage/user-notes.php?action=delete+23652 http://master.php.net/manage/user-notes.php?action=reject+23652
