php中如何header出状态代码转

在照彭武兴先生的《php bible》中所述,header可以送出status标头,如 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        | “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        | “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
