如何用PHP来取 http header 中的变量? 怎么没人回答呀,http header中的变量是怎么加进去的,是不是能自己来定义呀,也就是说,我想通过 http header 来传递变量,应该如何来实现呀? 解决方案 » 免费领取超大流量手机卡,每月29元包185G流量+100分钟通话, 中国电信官方发货 header传递变量? 看看这个文章在照彭武兴先生的《PHP BIBLE》中所述,header可以送出Status标头,如 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 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 header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");header("Last-Modified: " . gmdate("D, d M Y H:i:s") . "GMT");header("Cache-Control: no-cache, must-revalidate");header("Pragma: no-cache");header("Location: http://123.456.com");header("Refresh: 20");。。。 获取http header用$_SERVER["ALL_HTTP"]就可以得到,可以用代码: print_r ($_SERVER); 查看一下 PHP 怎样将pdf文件转换成 图片(.jpg .gif .png 等) 用php开发wap网站的高手帮帮忙啊.
