获取cookie值
index.php

HTML code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/--><iframe src="main.php" style="display:''"></iframe>


main.php
PHP code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->setcookie("l_cookie","cookie值");


我现在想要在index.php里获取cookie值,怎么获取不到啊????
我是直接echo $_COOKIE["l_cookie"]的

------解决方案--------------------
别说index.php

就是main.php也没这个值,除非你setcookie后,马上赋值


要么放在index.php里赋值,同时赋值,,,要么借助js取值
------解决方案--------------------
设置cookie,是当前请求完成后才存到客户端的,所以在请求过程中是取不到当前设置的cookie值的(请求 未完成),只能取到上次访问时设置的cookie值。
像楼上说的,刷新下就有了,相当于第2 次访问的时候获取第一次访问时设置的cookie
