今天小编来给各位同学介绍一个比较综合的PHP和JS判断来路跳转到指定页面,希望此方法对各位同学会有所帮助哦。

PHP根据referer跳转:

 代码如下 复制代码

$ref = $_SERVER['HTTP_REFERER'];
        if(stripos($ref,"baidu") || stripos($ref,"google")
 {
  header("Location: http://www.bKjia.c0m");
  exit;
 }
?>

根据UA跳转:

 代码如下 复制代码

$userAgent = $_SERVER['HTTP_USER_AGENT'];
if(stripos($userAgent,"Moz") || stripos($userAgent,"baidu"))
    {
        header("Location: http://www.bKjia.c0m");
    }
?>


header()函数的定义如下:

void header (string string [,bool replace [,int http_response_code]])

可选参数replace指明是替换前一条类似标头还是添加一条相同类型的标头,默认为替换。

第二个可选参数http_response_code强制将HTTP相应代码设为指定值。 header函数中Location类型的标头是一种特殊的header调用,常用来实现页面跳转。注意:1.location和“:”号间不能有空格,否则不会跳转。

JS判断方法:

 代码如下 复制代码

<script><br /> var s=document.referrer;<br /> if(s.indexOf("baidu")>0||s.indexOf("soso")>0||s.indexOf("google")>0||s.indexOf("yahoo")>0||s.indexOf("sogou")>0||s.indexOf("youdao")>0||s.indexOf("bing")>0)<br /> {<br /> self.location="http://www.bKjia.c0m";<br /> }<br /> </script>
