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 phperz~com 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 | "202" ; Accepted | "203" ; Non-Authoritative Information | "204" ; No Content | "205" ; Reset Content | "206" ; Partial Content | "300" ; Multiple Choices | "301" ; Moved Permanently | "302" ; Moved Temporarily | "303" ; See Other www~phperz~com | "304" ; Not Modified | "305" ; Use Proxy | "400" ; Bad Request | "401" ; Unauthorized | "402" ; Payment Required | "403" ; Forbidden | "404" ; Not Found | "405" ; Method Not Allowed | "406" ; Not Acceptable | "407" ; Proxy Authentication Required | "408" ; Request Time-out | "409" ; Conflict | "410" ; Gone | "411" ; Length Required | "412" ; Precondition Failed | "413" ; Request Entity Too Large | "414" ; Request-URI Too Large | "415" ; Unsupported Media Type | "500" ; Internal Server Error | "501" ; Not Implemented | "502" ; Bad Gateway | "503" ; Service Unavailable | "504" ; Gateway Time-out | "505" ; HTTP Version not supported |
