Summary of page jump methods in PHP development, PHP development page jump

Page jump may be triggered by the user clicking on a link, button, etc., or it may be triggered by the system Automatically generated. Automatic page jump is often used in WEB development, and different jump methods can be used according to needs, such as delayed jump after prompting operation information, etc. This article summarizes several common page jump methods in WEB development.

PHP header() function jump

PHP’s header() function is very powerful, and it is also simple to call when it comes to page url jump. Use header() to jump directly to the specified url page. At this time, the page jump is a 302 redirect:

 
$url = "http://www.bkjia.com/";  
header( "Location: $url" ); 

We may encounter special jumps. For example, when the website is revised and a page address needs to be 301 redirected, of course you can achieve this through web configuration rewrite, but now I want to tell you that you can use the PHP header. () function does a 301 jump, the code is as follows:

//301跳转 
header( "HTTP/1.1 301 Moved Permanently" );   
header( "Location: $url" ); 

Meta setting jump

You can directly set the jump in the meta information in HTML. You can set the jump delay time and jump URL. It is often used. For example, after the payment is completed, it tells the user that the payment is successful and jumps to the order page. The code is very simple, just in < ;head> add a sentence:

<meta http-equiv="refresh" content="5;url=http://www.bkjia.com"> 

The above code means that the page will automatically jump to http://www.bkjia.com after 5 seconds.

Javascript jump

Javascript jump is also very simple, just one sentence:

<script> 
window.location.href="http://www.bkjia.com"; 
</script> 

Note that after the above code jumps directly, the referer (also called the source) cannot be obtained in the target page address. In actual projects, when there are customers who require the jump to bring the referer ( That is, the target webpage can get the page from where it jumps). At this time, we can use javascript to simulate a click, and then the jump will meet the customer's needs.

<script> 
//有来路 
var aa = document.createElement("a"); 
aa.setAttribute("href","http://www.bkjia.com"); 
var bodys=document.getElementsByTagName("body")[0]; 
bodys.appendChild(aa); 
aa.click(); 
</script> 

Of course, in actual development, we can integrate the latter two methods into PHP to facilitate various jump requirements.
