SplStack::__construct — Constructs a new stack implemented using a doubly linked list
This constructs a new empty stack.
注意:
This method automatically sets the iterator mode to SplDoublyLinkedList::IT_MODE_LIFO.
此函數沒(méi)有參數。
示例 #1 SplStack::__construct() example
<?php
$q = new SplStack();
$q[] = 1;
$q[] = 2;
$q[] = 3;
foreach ($q as $elem) {
echo $elem."\n";
}
?>
