PHP header('位置：' . $url) http1.0 vs http1.1 vs？
我正在使用 PHP 进行一些重定向，例如：
header('Location: '.$url);
但现在我需要使用其他一些状态代码进行一些重定向。
我应该为此使用http1.0还是http1.1。或者我们已经达到了 http2.0 或更高版本？
两者的状态代码是否相同？
假设我想使用状态代码 404（未找到）进行重定向。
我可以这样做吗：
header('HTTP/1.1 404 Not Found');
header('Location: '.$url);
或者有一个：
header('HTTP/2.0 404 Not Found');
header('Location: '.$url);
I'm doing some redirects using PHP, e.g.:
header('Location: '.$url);
But now I need to do some redirects with some other statuscodes.
Should I http1.0 or http1.1 for this. Or are we already at http2.0 or greater?
And are the status code the same for both?
So let's say I want to redirect using statuscode 404 (Not Found).
Can I just do:
header('HTTP/1.1 404 Not Found');
header('Location: '.$url);
Or is there a:
header('HTTP/2.0 404 Not Found');
header('Location: '.$url);

一般来说，浏览器使用的是 HTTP 1.1（HTTP 1.0 已经很老了；并且不支持当今非常需要的几个有趣的功能）
HTTP 2.0？不存在这样的事情；-)
Don't hesitate to take a look at [Hypertext Transfer Protocol][1] -- and going through [**RFC 2616 - Hypertext Transfer Protocol -- HTTP/1.1**][2] can be a good idea.
是的，阅读本文可能需要一些时间——但如果您每天都在使用 HTTP，那么了解一点可能是个好主意；-)
Generally speaking, browsers are using HTTP 1.1 (HTTP 1.0 is quite old ; and doesn't support several interesting features which are pretty much required nowadays)
HTTP 2.0 ? There is no such thing ;-)

Yes, it can take some time to read this -- but if you are working every day with HTTP, knowing a bit about it can be a good idea ;-)
没有HTTP/2.0； HTTP/1.1 是最新版本。
您可以使用
$_SERVER['SERVER_PROTOCOL']的值以相同的协议版本进行响应：此时您应该意识到，如果响应是 HTTP/1.0，则 HTTP/1.1 标头字段可能将被忽略。
顺便说一句：Location标头字段 仅针对状态代码 201 和 3xx 定义：
There is not HTTP/2.0; HTTP/1.1 is the latest version.
You can use the value of
$_SERVER['SERVER_PROTOCOL']to respond with the same protocol version:At this point you should be aware that if the response is HTTP/1.0 the HTTP/1.1 header fields probably will be ignored.
By the way: The Location header field is only defined for the status codes 201 and 3xx:
请参阅
header()的第三个参数 用于发送特定状态代码：See the third parameter to
header()for sending a specific status code:如果您发送
HTTP/1.0还是HTTP/1.1，这取决于您，因为对于您的目的来说，没有任何改变。Its up to you, if you send
HTTP/1.0orHTTP/1.1, because for your purposes nothing changed.使用
HTTP/1.1。目前称为 HTTPbis 的 HTTP 的下一个版本将只是一个更新，仍然称为HTTP/1.1。Location:标头独立于协议版本工作。请注意，并非所有Status:号码都允许使用它们。只有范围 200-400 才应该使用它。对于 500 个错误，它肯定会被忽略。Use
HTTP/1.1. The next version of HTTP currently known as HTTPbis will just be an update, and still be called HTTP/1.1.The
Location:header works independently from the protocol version. Note that not allStatus:numbers allow them. Only ranges 200-400 should use it. For 500 errors it will certainly be ignored.
