数组的循环取值,但每次只去一个值,有可能实现吗
假设一个数组
$ar=array(1,2,3,4,5,6,7,8,9);

第一次响应取出1,第二次取出2,这可能实现吗?

直接在网页实现,代码越简洁越好,不在乎执行效率问题。


------解决方案--------------------
session_start();<br />
$ar = array(1,2,3,4,5,6,7,8,9);<br />
if(! isset($_SESSION['offs'])) $_SESSION['offs'] = 0;<br />
echo $ar[$_SESSION['offs']];<br />
$_SESSION['offs'] = ($_SESSION['offs'] + 1) % count($ar);<br />
Copy after login
