php:Header

转自鸟哥的博客: http://www.laruence.com/2007/12/16/308.html

PHP header()
the function declaration: void header ( string string [, bool replace [, int http_response_code]])
The optional replace parameter indicates whether the header should replace a previous similar header, or add a second header of the same type. By default it will replace(true);
RFC2616有相关的所有的状态信息的说明, 就状态码,大体总结如下:
* 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
So, 举几个例子:

header(“HTTP/1.1  Not Found”, true, );
header(“HTTP/1.0 Unauthorized”);
header(“Content-Type: text/html; charset=utf-;”);

header(“Location:http://www.xxx.com”);
