PHP Explode Each Character Function

This function is like PHP's explode() funtion, but instead of having a delimiter, it separates each character into it's own array piece.

For example, explodeEachChar('cat') would return array(0 => 'c', 1 => 'a', 2 => 't').

<?php

function explodeEachChar($x) {
    $c = array();
    while (strlen($x) > 0) {
        $c[] = substr($x,0,1);
        $x = substr($x,1);
    }
    return $c;
}

?>

Note: Of course, if you're on PHP 5 or greater, this can be done more simply using PHP's built-in str_split() function.

Thanks for the code. Just for future reference to anyone else using this:

Replace: while (strlen($x > 0))
With: while (strlen($x) > 0)

Otherwise it misses out the last character of the string.

Thanks Lyndon. You're right, I had a typo. I fixed it in the code up above too.
