此函數沒(méi)有參數。

UnderflowException if empty.
示例 #1 Ds\Stack::pop() example
<?php
$stack = new \Ds\Stack();
$stack->push("a");
$stack->push("b");
$stack->push("c");
var_dump($stack->pop());
var_dump($stack->pop());
var_dump($stack->pop());
?>
以上例程的輸出類(lèi)似于：
string(1) "c" string(1) "b" string(1) "a"
