The problem of PHP jumping to a specified page is usually seen in website construction requirements. For example, we need to jump from one page to another to achieve a certain function or effect. In fact, there are many ways to jump pages in PHP, so this article will introduce to you, what methods can be used to jump pages in PHP?

First of all, we need to understand two knowledge points:

1: 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.

2: The Meta tag is a tag in HTML that is 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.

Then the specific example code for using the header() function of php to jump to the specified page is as follows:

void header (string string [,bool replace [,int http_response_code]])//header()函数的定义

Copy after login

<  ?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;
?>

Copy after login

The specific example code for using the Meta tag for php to jump to the specified page is as follows:

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

Copy after login

< ?php   
$url= "http://www.php.cn/" ;?>  
<html>    
<head>    
<meta   http-equiv = "refresh"   content ="1;  
url = <?php echo $url;  ?> ">    
</head>    
<body>    
页面只停留一秒……   
</body>  
</html>
//meta.php实现在该页面中停留一秒后页面自动跳转到www.php.cn

Copy after login
