TalkPHP - View Single Post - Part 1: Getting Started with Array Functions

To further the last post, above, there is also the array_walk function which behaves similarly (but not the same!) as array_map.

array_walk (PHP manual page)
This does the same thing as the array_map example above.

PHP Code:


			
array_walk($MyInputArray, 'htmlspecialchars');

The important difference being that array_walk acts on the array itself, whereas array_map acts on a copy of it (sort of) by default.
