PHP page jump 1. header() function

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

header() function is defined as follows:

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

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

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 the header.

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

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

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, the following program meta.php implements staying on the page for one second The next page will jump automatically.

<?php     
$url = "http://blog.csdn.net/abandonship";   
?>   
<html>     
<head>     
<meta http-equiv="refresh" content="1;url=<?php echo $url; ?>">     
</head>     
<body>   
It&#39;s transit station.  
</body>  
</html>
