note 45376 added to function.array-walk

one rather important note that was lost in the Great PHP Doc Note Purge of '04 is that you can call methods using array_walk(). Let's assume that we have a class named 'Search', in which there is a method called 'convertKeywords'. Here's how you would call that convertKeywords method from inside the class: array_walk($keywords, array($this, 'convertKeywords')); Notice that, instead of giving a string as the second argument, you give an array with two items: the variable that holds the class (in this case, $this), and the method to call. Here's what it would look like if you were to call convertKeywords from an already-instantiated class: $search = new Search; array_walk($keywords, array($search, 'convertKeywords')); ---- Manual Page -- http://www.php.net/manual/en/function.array-walk.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+45376 Delete -- http://master.php.net/manage/user-notes.php?action=delete+45376&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+45376&report=yes Search -- http://master.php.net/manage/user-notes.php
