This is a tool to write a small code template for array_walk(). It also demonstrates using JavaScript to generate code -- view source to see this. Perl has a nice feature called "map". It's similar to array_walk(), except not clunky. It looks like this: map( function, @array ); OR map { ... } @array; This latter form is powerful. You can stack it like this: map { ... } ( map { ... } @array ); PHP lacks this nice syntax. It does, however, have array_walk(), and that can work in a pinch. Below is a form that writes a little bit of array_walk() code for you. Type a variable name, and press TAB.
