What are the PHP page jump codes?

The PHP page jump codes are:

1. PHP page jump 1. header( ) Function

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]])
Copy after login

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 parameterhttp_response_codeForce 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: There cannot be a space between

  • location and the ":" sign, otherwise the jump will not occur.

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

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

For example, redirect the browser to my website:

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

2. PHP page jump 2. Meta tag

The

Meta tag is a tag in HTML responsible for providing document meta-information. Using this tag in a PHP program can also achieve page jumps. 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/">
Copy after login

For example, the following program meta.php implements the page to automatically jump to www.bbseat.com.cn after staying on the page for one second.

<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>
Copy after login

3. PHP page jump 3. JavaScript

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

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