PHP中如何使用header发送头部信息

网络整理 - 08-17

以下为引用的内容:

<?php
  
  header("Status: 404 Not Found");
  
  ?>
 

就可以让用户浏览器出现文件找不到的404错误,但是我试了这样是不行的。
  
       后来我到w3.org上查了http的相关资料,终于试出来了如何Header出状态代码(Status),与大家分享。
  
       其实应该是这样的:

以下为引用的内容:

 Header("http/1.1 403 Forbidden");
  
  ?>
 


第一部分为HTTP协议的版本(HTTP-Version)
  
  第二部分为状态代码(Status)
  
  第三部分为原因短语(Reason-Phrase)
  
  三部分中间用一个空格分开,且中间不能有回车,第一部分和第二部分是必需的,第三部分则是给人看的,可写可不写甚至乱写。
  
  还有,这一句的输出必须在Html文件的第一行。
  
  下面我给出各代码所代表的意思(是从w3.org上查到的,够权威了):
  
  * 1xx: Informational - Request received, continuing process
  
  * 2xx: Success - The action was successfully received, understood,
  
  and accepted
  
  * 3xx: Redirection - Further action must be taken in order to
  
  complete the request
  
  * 4xx: Client Error - The request contains bad syntax or cannot be
  
  fulfilled
  
  * 5xx: Server Error - The server failed to fulfill an apparently
  
  valid request
