如何在PHP中返回http statuscodes？

Question

可能重複：
return a specific http status code with php

我如何以編程方式發送特定的HTTP statuscodes用PHP？ 有沒有任何方法，甚至是類？

Answer 1

header()函數是你所需要的。

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

把它放在右後第一<?php標記爲腳本呈現響應輸出。

你應該參考http://php.net/manual/en/function.header.php

Answer 2

看那header()功能：

header('HTTP/1.0 404 Not Found'); 

把那個腳本的任何輸出之前。

Answer 3

發送您發送任何東西給客戶header()之前。一些可能的狀態標題如下：

header('HTTP/1.1 200 OK'); 

// Page was not found: 
header('HTTP/1.1 404 Not Found'); 

// Access forbidden: 
header('HTTP/1.1 403 Forbidden'); 

// The page moved permanently should be used for 
// all redrictions, because search engines know 
// what's going on and can easily update their urls. 
header('HTTP/1.1 301 Moved Permanently'); 

// Server error 
header('HTTP/1.1 500 Internal Server Error'); 

// header for telling the browser that the content 
// did not get changed 
header('HTTP/1.1 304 Not Modified');
