how to explode a string using a foreach

I got this string

$string = '1:23:health,2:24:mana';
$v = explode(",", $string);
foreach($v as $data)
{
    echo $data[0][1];
}

What im looking is to making a "multidimensional string" by exploding ‘,’

Wanna do this:

data[0][0] = 1;
data[0][1] = 23;
data[0][2] = "health";

How can i do this in PHP?

>Solution :

$string = '1:23:health,2:24:mana';

$result = [];
foreach (explode(',', $string) as $step) {
  $result[] = explode(':', $step);
}

print_r($result);

An alternative is:

$string = '1:23:health,2:24:mana';

$result = array_chunk(preg_split('/[:,]/', $string), 3);

print_r($result);
