Howto split a string into character groups in actionscript?

Question

I need a string splitted into groups of characters in ActionScript like this:

var txt:String = "Hello World";
var arr:Array = txt.split(3);
// Now arr should contain a value like: ["Hel", "lo ", "Wor", "ld"]

This is possible in PHP like this:

$arr = str_split(txt, 3);

But I need a ActionScript equivalent of this PHP code.

You can use a regex:

var txt:String = "Hello World";
var arr:Array = txt.match(/.{3}|.+/g);
trace(arr);
// Hel,lo ,Wor,ld
