在照彭武兴先生的《PHP BIBLE》中所述,header可以送出Status标头,如
<?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:

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


       "100" ; Continue

       "101" ; Switching Protocols

       "200" ; OK

       "201" ; Created

       "414" ; Request-URI Too Large

       "415" ; Unsupported Media Type
