Be careful SplStack mode is LIFO (Last In First Out) not FIFO (First in First Out) 
<?php
// Array (FIFO)
$stack = array();
array_push($stack,"orange");
array_push($stack,"banana");
array_push($stack,"apple");
array_push($stack,"raspberry");

var_dump($stack);
?>
// result

array (size=4)
  0 => string 'orange' (length=6)
  1 => string 'banana' (length=6)
  2 => string 'apple' (length=5)
  3 => string 'raspberry' (length=9)

<?php
// SplStack (LIFO)
$stack = new SplStack();
$stack ->push('orange');
$stack ->push('banana');
$stack ->push('apple');
$stack->push('raspberry');

$stack->rewind();
while(
$stack->valid()){
   
var_dump($stack->current());
   
$stack->next();
   
}
?>
//result 
string 'raspberry' (length=9)
string 'apple' (length=5)
string 'banana' (length=6)
string 'orange' (length=6)

You can also push an element at the end of the doubly linked list like in a simple array with square brackets:

$spl = new SplDoublyLinkedList;

$spl[] = 1;
$spl[] = 2;
$spl[] = 3;
$spl[] = 4;

print_r($spl);
