   echo "An array is: \n";
   #using toArray() function
   print_r($queue->toArray());
?>

Ds\Queue Object
(
    [0] => 10
    [1] => 20
    [2] => 30

   #using toArray() function
   $arr = $queue->toArray();
   echo "An array is: \n";
   print_r($arr);
?>

The original queue is:
Ds\Queue Object
(
    [0] => Tutorials
    [1] => Point
    [2] => India
