请问下   我建立了一个公共的文件用于保存信息 conn.php

$isLog = true;

我想在a.php中把$isLog = false;

但是我在b.php中查询$isLog还是true


请问下 是不是没理解对  


回复讨论(解决方案)

要达到你要的效果,用session存吧。

conn.php文件内的$isLog = true;

你在a.php引用conn.php,把值改成false 但是conn.php文件本身的值没有改变
在你b.php重新引用conn.php 的时候 获取的值肯定还是true

要达到你的效果,用get传递、用session都可以

如果想要在页面改变加载变量的值,只需在当前页面重写该变量,注意加载页面和重写变量顺序。
