The expression $strings of type array is implicitly converted to a boolean; are you sure this is intended? If so, consider using ! empty($expr) instead to make it clear that you intend to check for an array without elements.

      preg_match('/^(\s+)/', $strings[0], $matches);
      $indentation_size = isset($matches[1]) ? strlen($matches[1]) : 0;
      foreach ($strings as $key => $string) {
        $strings[$key] = substr($string, $indentation_size);
      }
