I think that adding this line

PHP Code:

    $folder = substr($filename, 0, $pos); 


right above this line

PHP Code:

    $filename = substr($filename, $pos+1); 


Should give you the full path (only folders) to the file.
Then you can use $folder for some if statements inside this:

PHP Code:

  case 'index.php':
    $userinfo[activity] = 'index';
    break; 


i.e:

PHP Code:

  case 'index.php':
    if (strstr ($folder, "math")) {
      $userinfo[activity] = 'math';
    } elseif (strstr ($folder, "english")) {
      $userinfo[activity] = 'english';
    } else {
      $userinfo[activity] = 'index';
    }
    break; 


I think that will work.
