在照彭武興先生的《PHP BIBLE》中所述,header可以送出Status標頭,如
<?php

header("Status: 404 Not Found");

?>

就可以讓用戶瀏覽器出現(xiàn)文件找不到的404錯誤,但是我試了這樣是不行的。

后來我到w3.org上查了http的相關資料,終于試出來了如何Header出狀態(tài)代碼(Status),與大家分享。

其實應該是這樣的:

Header("http/1.1 403 Forbidden");

?>

第一部分為HTTP協(xié)議的版本(HTTP-Version)

第二部分為狀態(tài)代碼(Status)

第三部分為原因短語(Reason-Phrase)

三部分中間用一個空格分開,且中間不能有回車,第一部分和第二部分是必需的,第三部分則是給人看的,可寫可不寫甚至亂寫。

還有,這一句的輸出必須在Html文件的第一行。

下面我給出各代碼所代表的意思(是從w3.org上查到的,夠權威了):

  * 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
