PHP自动“获取"变数 [英] PHP Automatically "GET" Variables

问题描述

我正在为公司设计一个新的网站，并且试图实现开关导航，这是我过去在所有站点上使用的导航.

I am desiging a new website for my company and I am trying to implement switch navigation which is what I have used on all my sites in the past.

<?php
switch($x) {

default:
include("inc/main.php");
break;

case "products":
include("inc/products.php");
break;

}
?>

由于某种原因，当我转到index.php?x = products时，什么都没发生，它仍然显示inc/main.php，换句话说，它没有从URL中检测到X变量.这和全局变量有关吗?

For some reason when I go to index.php?x=products nothing happens, it still displays inc/main.php, in other words it hasn't detected the X variable from the URL. Is this something to do with global variables?

推荐答案

是的，您的PHP配置正确已关闭register_globals，因为这确实不安全.

Yes, your PHP configuration has correctly got register_globals turned off, because that's incredibly insecure.

只需输入:

$x = $_REQUEST['x']

位于脚本顶部.

如果只希望它对GET HTTP方法有效，也可以使用$_GET.我见过有人声称$_REQUEST某种程度上是不安全的，但是没有证据支持这一点.

You can also use $_GET if you specifically only want this to work for the GET HTTP method. I've seen some people claim that $_REQUEST is somehow insecure, but no evidence to back that up.
