      PHP中怎么使用header發送上端信息

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

      header("Status: 404 Not Found");

      ?>

      就可以讓用戶瀏覽器出現文件找不到的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協議的版本(HTTP-Version)

      第二部分為狀態代碼(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
