问题描述
我想要做的就是从PHP发送一个 404
状态码 - 但是采用通用的方式。无论是 Router :: statusCode(404)
还是 Router :: statusCode(403)
都可以工作,有效的HTTP状态码。 我知道,您可以指定一个状态码作为第三个参数。可悲的是,这只有在指定字符串
时才有效。因此,调用 header('',false,404)
不会 工作。此外,我知道,可以通过标头
调用发送状态码,状态栏为:标头('HTTP / 1.1 404 Not Found')
但要做到这一点,我必须保留一组理由短语( Not Found
)为所有状态代码( 404
)。我不喜欢这个想法,因为它以某种方式重复了PHP自己已经做了什么(对于第三个头
参数)。
所以,我的问题是:是否有任何简单而干净的方式在PHP中发送状态码?
在PHP> = 5.4.0中有一个新的函数
只需执行 http_response_code(404)
。
如果您的PHP版本较低,请尝试 header('',true,404);
(注意字符串中的空格)。
如果您想设置原因词组,请尝试:
header('HTTP / 433 Reason Phrase As You Wish');
All I want to do, is send a 404
status code from PHP - but in a generic fashion. Both Router::statusCode(404)
and Router::statusCode(403)
should work, as well as any other valid HTTP status code.
I do know, that you can specify a status code as third parameter to header
. Sadly this only works if you specify a string
. Thus calling header('', false, 404)
does not work.
Furthermore I know, that one can send a status code via a header
call with a status line: header('HTTP/1.1 404 Not Found')
But to do this I have to maintain an array of reason phrases (Not Found
) for all status codes (404
). I don't like the idea of this, as it somehow is a duplication of what PHP already does itself (for the third header
parameter).
So, my question is: Is there any simple and clean way to send a status code in PHP?
There is a new function for this in PHP >= 5.4.0 http_response_code
Simply do http_response_code(404)
.
If you have a lower PHP version try header(' ', true, 404);
(note the whitespace in the string).
If you want to set the reason phrase as well try:
header('HTTP/ 433 Reason Phrase As You Wish');
