how to explode or split or chunk in an efficient way

[Negin Nickparsa <nickparsa@xxxxxxxxx>]

I have a string which always has "C" then a number which it's length can
change anytime and then "P" and then a space and then a word

like:

echo "C60P1 Unit";

is it anyway to split the string by type?

from the manual I did this:

function multiexplode ($delimiters,$string) {
    $ary = explode($delimiters[0],$string);
    array_shift($delimiters);
    if($delimiters != NULL) {
        foreach($ary as $key => $val) {
             $ary[$key] = multiexplode($delimiters, $val);
        }
    }
    return  $ary;
}
echo "C60P1 Unit";
$str="C60P1 Unit";
$delimiters = Array("C","P"," ");
$res = multiexplode($delimiters,$str);
echo '<pre>';
print_r($res);
echo '</pre>';

but it seems to me it is so complex for such a small string
does anything for type exist which I don't know about to for example just
grab the numbers?because I just care about the numbers here 60 and 1
seperately
