$_SERVER['regerer']的用法
比如我在每个页面都用$_SERVER['referer']验证用户过来的网址是不是我的页面
那如果用户是通过百度等搜索引擎过来的,那会通过这个验证吗?

如果不行的话要怎么排除这个问题呢?

谢谢!

------解决方案--------------------
好像是HTTP_REFERER吧?
------解决方案--------------------
只要是通过连接过来的,$_SERVER['HTTP_REFERER'] 都表示连接所在的页面
当然也可能用某种手段产生虚假的 $_SERVER['HTTP_REFERER']
------解决方案--------------------
是嘀,$_SERVER['HTTP_REFERER']可以伪造,如果重要判断,只能做为参考。
------解决方案--------------------
某种程度上用apache可以控制控制
------解决方案--------------------
