php string explode for binary code

Question

I'm on search for a php snipped to cut following binary code:

$code = "10011";

I need from $code an explode array like $codes = array(100,1,1); for example:

echo $codes[0]; // echo result: 100

I'm not sure what php function is helpful, thank you very much for help!

With a regex, a 1 with zero or more 0:

preg_match_all('~10*~', $str, $m);
print_r($m[0]);

If your string eventually starts with one or more zeros, you can change it to:

preg_match_all('~10*|0+~', $str, $m);

wow! that's smart solution. thank you very much, you made my day :)

and if I need 1000101 = 1000000, 100, 1 one more example: 101001100 = 100000000, 1000000, 1000, 100

@Korty: something like this or this but I'm sure there's a better way to do that.

@Korty: refresh the page, I edited the comment. Better, this one

@Korty: I'm sure you will find how to do it.
