PHP function to rekey or index a multidimensional array and preserve associative keys

rekey_multi_array.php

<?php
function rekey_multi_array($array) {
	$new = array();
	$count = 0;
	if (is_array($array)) {
		foreach ($array as $key => $val) {
			if (!is_numeric($key)) {
				$new[$key] = $this -> rekey_multi_array($val);
			} else {
				$new[$count] = $this -> rekey_multi_array($val);
				$count++;
			}
		}
		return $new;
	} else {
		return $array;
	}
}
?>

Works great!
