Breaking a string into characters and numbers separately

I have a string like

HCl3C24

I want to break this string in php like 

array(0 => H , 1 => Cl, 2 => 3 , 3 => C, 4 => 24)

Right now I am trying :

$matches = array();
$string = "HCl4";
preg_match_all('/([0-9]+|[a-zA-Z]+)/',$string,$matches);
print_r($matches[0]);

It's not working for characters but numbers. Could anyone please help me here ?

You can also access each char of that string by treating it as an array:

$string = "HCl4";
echo $string[0] // prints H
echo $string[1] // prints C
echo $string[2] // prints l
echo $string[3] // prints 4

use this regex:

/([0-9]+|[a-zA-Z])/

if you want [ "H", "Cl", 3, "C", 24 ] then

/([0-9]+|[A-Z][a-z]*)/
