PHP: Split string into array, like explode with no delimiter

I have a string such as:

"0123456789"

And I need to split each character into an array.

I, for the hell of it, tried:

explode('', '123545789');

But it gave me the obvious: Warning: No delimiter defined in explode) ..

How would I come across this? I can't see any method off hand, especially just a function.

$array = str_split("0123456789bcdfghjkmnpqrstvwxyz");

str_split takes an optional 2nd param, the chunk length (default 1), so you can do things like:

$array = str_split("aabbccdd", 2);

// $array[0] = aa
// $array[1] = bb
// $array[2] = cc  etc ...

You can also get at parts of your string by treating it as an array:

$string = "hello";
echo $string[1];

// outputs "e"

You can access characters in a string just like an array:

$s = 'abcd';
echo $s[0];

prints 'a'

Try this:

$str = '123456789';
$char_array = preg_split('//', $str, -1, PREG_SPLIT_NO_EMPTY);
