怎么防止别人下载或访问PHP配置文件

防止直接访问、查看或下载config.php文件的方法

防止别人下载或访问你的PHP配置文件？

假如你的配置文件为config.php，其中有访问数据库的用户名和密码，你肯定不想让人看到或下载

这里给出一个解决方法，这也是很多php程序中常用的方法，供大家参考。

1、先定义标识变量

代码如下:

define(&#39;IN_SYS&#39;, TRUE);

2、在config.php中获取这变量

代码如下:

if (!defined(&#39;IN_SYS&#39;)) {
　　exit(&#39;禁止访问&#39;);
}

这样就实现了未经定义的随意查看或下载了。
