Q:

how to trim a string into two Integers and one string (php)?

I have a question variable e.g. "4X9"
how can i split this into 3 different variables, to have an integer 4, integer 9 and string X ? 
I tried using 
$arr = explode('X', $question);
    $before = $arr[0];

    $bbefore = str_replace('"', "", $before);
  $newBefore =(int)$before;`

and the same for after. 

A:

list($before, $x, $after) = str_split(str_replace('"', '', $question));

1) Explode string by character using str_split()
2) Use list() to make assigning them variables clearer
3) If $before and/or $after are integers you can cast them after this line of code
list($before, $x, $after) = str_split(str_replace('"', '', $question));   
$before = (int) $before;   
$after  = (int) $after;
