php implements 301 reload Directional jump

After searching around the Internet, it was all done using

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

and then combined with

header('Location: https://www.php.cn');

.

I always feel like I can’t finish one sentence, and besides, HTTP/2 has been out for a long time, and I still wrote HTTP/1.1 to watch. It doesn’t feel good. Of course, it’s okay to write HTTP/2 or HTTP/1.0, but no matter what you write, there is always a feeling of unclear expression (for example, HTTP/ 1.1 is HTTP/2 during actual access - when accessing, it is still HTTP/2 when it should be HTTP/2. There will be no problem and no confusion. ChangeHTTP/1.1)

Go to php.net and search again, and find that the Header can be used like this

header ( string $header [, bool $replace = TRUE [, int $http_response_code ]] )

This is easy to handle, in one sentence

header('Location: https://www.php.cn', true, 301);

It’s done, hahahahahahaha

One more thing, if you want to adapt HTTPS/HTTP, this is enough:

header('Location: //www.php.cn', true, 301);
