the SplStack is  simply a SplDoublyLinkedList with  an iteration mode IT_MODE_LIFO and IT_MODE_KEEP

<?php

//SplStack Mode is LIFO (Last In First Out)

  

$q = new SplStack();



$q[] = 1;

$q[] = 2;

$q[] = 3;

$q->push(4);

$q->add(4,5);



$q->rewind();

while($q->valid()){

    echo $q->current(),"\n";

    $q->next();

}

?>



Output
