How to use php to achieve page jump

The way to use PHP to implement page jump is to use the header() function to implement the jump, such as [header("Location: http:// www.xxxxx.com");].

It is very simple to implement page jump in php. For example, we can use the header() function or use Meta tag to implement page jump.

Let’s take a look at these two methods of page jump.

Method 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 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, which is 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, redirect the browser to IceLove.com

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

Method 2: Meta tag

Meta tag is a tag in HTML responsible for providing document meta-information. Using this tag in PHP programs 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 will take for the page to jump to the specified URL. For example, use meta tags to realize that the page automatically jumps to Ice Love after the vaccine.

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

For example, the following program meta.php implements the page to automatically jump to bbs.lampbrother.net after staying on the page for one second.

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