Detailed explanation of matters needing attention in 301/404 jump in PHP header_PHP Tutorial

If 301 or 404 appears on your webpage, it is a very serious problem for the user experience, so we must be more careful when doing php header301 or 404. Let me take a look.

301 jump

The code is as follows

代码如下	复制代码
header('HTTP/1.1 301 Moved Permanently');   header('Location: http://www.abc.com/aaa/');   exit();

Copy code

header('HTTP/1.1 301 Moved Permanently');
header('Location: http://www.abc.com/aaa/');
exit();

代码如下	复制代码
header("HTTP/1.1 404 Not Found");

Don’t miss the header(‘HTTP/1.1 301 Moved Permanently’); otherwise 301 will not be returned

代码如下	复制代码
header("Status: 404 Not Found");

404 error page

代码如下	复制代码
header("HTTP/1.1 404 Not Found"); header("Status: 404 Not Found");
