php code to implement page jump: [header("Location:http://www.xxxxxx.com.cn/");]. The header function is a very simple method for page jump. Its main function is to output the HTTP protocol header to the browser.

Method 1: header() function

(Learning video recommendation: java course)

## The #header() function is a very simple method for page jump in PHP. The main function of this function is to output the HTTP protocol header (header) to the browser.

The function is defined as follows:

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

Optional parameter replace indicates 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 corresponding 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.

2. There cannot be any output before using header, not even a space.

3. The PHP code after the header will also be executed.

Example:

//重定向浏览器
header("Location:http://www.bbsss.com.cn/");
//确保重定向后，后续代码不会被执行 
exit;

Method 2: Meta tag

The Meta tag is a tag in HTML responsible for providing document meta-information. It can also be implemented by using this tag in a PHP program Page jump. If http-equiv is defined as refresh, when the page is opened, it will jump to the corresponding page within a certain period of time based on the value specified by content.

If content="seconds;url=website" is set, it defines how long it takes for the page to jump to the specified URL. For example, use the meta tag to automatically jump to my website after the vaccine.

<meta http-equiv="refresh" content="1;url=http://www.bbseat.com.cn/">

Example:

<html>
<head>
<meta http-equiv="refresh" content="1; url=http://www.bbseat.com.cn/">
</head>
<body>
页面只停留一秒……
</body>
</html>

Method 3: JavaScript

For example, this code can be placed in any legal location in the program.

$url = "http://www.bbsss.com.cn/"; 
echo "<script language=&#39;javascript&#39; type=&#39;text/javascript&#39;>";
echo "window.location.href=&#39;$url&#39;";
echo "</script>";
