It's worth noting that you can also address individual characters in a
string like an array:

$str = '3567';
echo $str{2};

will output '6'.

If you really needed it to be an array then you could do something
like this:

function str_to_array($str) {
$a = array();
$len = strlen($str);

for($i = 0; $i < $len; $i++)
$a[$i] = $str{$i};

return $a;
}
