SplStack¶
The SplStack class is part of the Standard PHP Library, SPL. It provides a stack data structure, Last‑In, First‑Out or LIFO, by extending SplDoublyLinkedList and setting the iteration mode to treat the list as a stack.
<?php
$q = new SplStack();
$q[] = 1;
$q[] = 2;
$q[] = 3;
foreach ($q as $elem) {
echo $elem.\n;
}
?>
