Question

Example of my string $number = '1,10,40';

How do I put the numbers into my foreach loop something like this.

foreach($array[$number[1]] as $one)
{
  foreach($array[$number[10]] as $two)
  {
     foreach($array[$number[40]] as $three)
     {
     }
  }
}

I think you will something like:

function recursive($input) {
    if(is_string($input) {
         return recursive(explode(',', $input);
    }
    if(is_array($input) && !empty($input)) {
        $to = array_shift($input);
        for($i=0;$i<=$to;$i++) {
            recursive($input);
        }
    }
    if(empty($input) {
        //do here whatever you want
    }
}
