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
