http - HTTP 状态代码的名称是否重要

Question

假设我正在用 PHP 发送一些 HTTP 状态代码，我真的需要这样做吗

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

或者是否足够

header('HTTP/1.1 301 FooBar');

我曾经在一个快速而肮脏的反向代理中这样做过，我只能从 CURL 响应中获取代码，而不是消息，然后将其作为消息发送回 FooBar。这似乎工作正常。

通过spec :

The individual values of the numeric status codes defined for HTTP/1.1, and an example set of corresponding Reason-Phrase's, are presented below. The reason phrases listed here are only recommendations -- they MAY be replaced by local equivalents without affecting the protocol.
