String to Character Array

[forum11]

How can I break an string to a an array of characters.
e.g;
$str = "123456";
then after breaking above string, character array would be
$arr = array('1','2','3','4','5','6');

str_split (see comments there about php4 compatibility).

For php4 just do this which is in php manual:

$str = 'two words';
$array = explode("\r\n", chunk_split($str,1));
print"<pre>";
print_r($array);

To show there is more then one way.

<?php

preg_match_all('/(\w)/', 'abcdefghijklmnopqrstuvwzyz', $regs);
print_r($regs[0]);
