    Yeah, error checking ...

    Can't search for '/^ wmax $/' because it just returns nothing.  Dropping the '$' at the end works.

    The array_shift() also drops the first variable because the explode() call breaks it up as:
        wmax = 5, 5, 5.4 ... etc.  First value = 'wmax = 5'

    And the explode also fails because data is not in $array[0], it's in $array[30].  Inserting an array_values() to reindex helps.

    So as of right now, I'm looking at:

      if ($array = preg_grep('/^ wmax = /', $output)) {
        $array = array_values($array);
        $wmax = explode(', ', $array[0]);
      }
      array_shift($wmax);
      print_r($wmax);

    The array_shift() call needs to shift out the 'wmax = ', but leave the first value.

    And, I still need to convert the whole thing into '$wmax = {5, 5, 5.4, ...}'.  Right now it's an array of strings:

        Array
        (
            [0] =>  wmax = 5
            [1] => 5
            [2] => 5
            [3] => 5.4
        )
