301 jump is to tell the visitor that the page has reached a new page forever. To use 301 jump in PHP, we use the header() function to send the 301 status code to tell the browser, and then implement the page jump.

PHP pure code jump

The code is as follows

Copy code

代码如下	复制代码
header("Location:http://www.bKjia.c0m/"); ?>

header("Location:http://www.bKjia.c0m/");

But the status code returned is 302

代码如下	复制代码
header( "HTTP/1.1 301 Moved Permanently" ) ; header("Location:http://www.bKjia.c0m/"); ?>

If you want to implement 301 jump, you need to set the status code before

The code is as follows	Copy code

代码如下	复制代码
$urlto='http://www.bKjia.c0m/'; header('Location: '.$urlto, TRUE, 301); ?>

header( "HTTP/1.1 301 Moved Permanently" ) ;

header("Location:http://www.bKjia.c0m/");

Simpler PHP jump 301 code

The code is as follows

Copy code

$urlto='http://www.bKjia.c0m/';

header('Location: '.$urlto, TRUE, 301);

Possible problems

Warning: Cannot modify header information - headers already sent by Changing the file encoding to UTF-8 without BOM format can solve this problem. If there is still a problem, check whether a string variable is defined before the code and delete this variable and try again.

Attachment: The difference between 30* return status codes

301 and 302 are both HTTP status codes, and both represent that a certain URL has been transferred. The difference is:

1.301 redirect: 301 represents Permanently Moved,
