php禁止直接从浏览器输入地址访问.PHP文件

http net php quot

对于有些重要的文件我们并不希望用户可以直接输入地址进行访问了,这我们需要进行一些设置下面总结了一些php禁止直接从浏览器输入地址访问.PHP文件方法,大家看看。

<script>ec(2);</script>

比如说我http://www.111cn.net /xx.php 这个文件我不想让别人直接从浏览器输入地址访问
但是如果从任何网站连接http://www.111cn.net /xx.php过来就可以访问
本机建立连接也无法访问跳转到另外的地址

1.在xx.php文件头部写上以下代码就可以了

$fromurl="http://www.111cn.net /"; //跳转往这个地址。
if( $_SERVER['HTTP_REFERER'] == "" )
{
header("Location:".$fromurl); exit;
}
这样只需要简单为造来源就可以了,我们如果真要做到,可以如下操作

2. 在程序中定义一个标识变量


define('IN_SYS', TRUE);


3. 在config.php中获取这变量


if(!defined('IN_SYS')) {
exit('禁止访问');
}

后面的两种方法是我们在很多cms中碰到的哦。
