Alternating string splits

[Outer]

I need to know how to break a string up into alternating sizes.

for example, I need this string broken up: "hi, how are you, peace!"
so results are like this:
"hi"
", h"
"ow"
" ar"
" y"
"ou "
", p"
"eac"
"e!"

Note the spaces. Basically, I need a string to be cut up by a pattern of 2 characters, then 3 characters, then 2 characters, then three characters

How would I do that in PHP?

Thank You

Try this (I think you forgot the 'e' in 'are' in your example =P)

	$string = 'hi, how are you, peace!';

	function customSplitString($text) {
		$text_pieces = array();
		$offset = 0;
		$piece_length = 2;
		$str_length = strlen($text);
		
		for ($x=0; $offset < $str_length; $x++) {
			$piece_length = ($x % 2) ? 3 : 2;
			$text_pieces[] = substr($text, $offset, $piece_length);
			$offset += $piece_length;
		}
		return $text_pieces;
	}

	print_r(customSplitString($string));
