PHP and JS determine the origin and jump to the specified page_PHP tutorial

Today, the editor will introduce to you a more comprehensive PHP and JS method to determine the source and jump to the specified page. I hope this method will be helpful to all students.

PHP jumps according to referer:

The code is as follows

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;  } ?>

Copy code

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");     } ?>

$ref = $_SERVER['HTTP_REFERER'];
If(stripos($ref,"baidu") || stripos($ref,"google") {

header("Location: http://www.bKjia.c0m");

exit;

}

?>

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>

Jump according to UA:

The code is as follows

Copy code

$userAgent = $_SERVER['HTTP_USER_AGENT']; if(stripos($userAgent,"Moz") || stripos($userAgent,"baidu")) { header("Location: http://www.bKjia.c0m"); } ?> The header() function is defined as follows: void header (string string [,bool replace [,int http_response_code]])

The optional parameter replace specifies whether to replace the previous similar header or add a header of the same type. The default is replacement.

The second optional parameter http_response_code forces the HTTP response code to the specified value. The Location type header in the header function is a special header call, often used to implement page jumps. Note: 1. There cannot be a space between location and ":", otherwise it will not jump. JS judgment method:

The code is as follows

Copy code

<script><🎜> var s=document.referrer;<🎜> if(s.indexOf("baidu")>0||s.indexOf("soso")>0||s.indexOf("google")>0||s.indexOf("yahoo")&gt ;0||s.indexOf("sogou")>0||s.indexOf("youdao")>0||s.indexOf("bing")>0)<🎜> {<🎜> self.location="http://www.bKjia.c0m";<🎜> }<🎜> </script> http://www.bkjia.com/PHPjc/632656.htmlwww.bkjia.comtruehttp: //www.bkjia.com/PHPjc/632656.htmlTechArticleToday, the editor will introduce to you a more comprehensive PHP and JS method to determine the origin and jump to the specified page.
