PHP中Header使用的HTTP协议及常用方法小结

本文实例总结了PHP中Header使用的HTTP协议及常用方法。分享给大家供大家参考。具体方法如下：

复制代码 代码如下:<?PHP
function https($num) {
$http = array (
100 => "HTTP/1.1 100 Continue",
101 => "HTTP/1.1 101 Switching Protocols",
200 => "HTTP/1.1 200 OK",
201 => "HTTP/1.1 201 Created",
202 => "HTTP/1.1 202 Accepted",
203 => "HTTP/1.1 203 Non-Authoritative Information",
204 => "HTTP/1.1 204 No Content",
205 => "HTTP/1.1 205 Reset Content",
206 => "HTTP/1.1 206 Partial Content",
300 => "HTTP/1.1 300 Multiple Choices",
301 => "HTTP/1.1 301 Moved Permanently",
302 => "HTTP/1.1 302 Found",
303 => "HTTP/1.1 303 See Other",
304 => "HTTP/1.1 304 Not Modified",
305 => "HTTP/1.1 305 Use Proxy",
307 => "HTTP/1.1 307 Temporary Redirect",
400 => "HTTP/1.1 400 Bad Request",
401 => "HTTP/1.1 401 Unauthorized",
402 => "HTTP/1.1 402 Payment Required",
403 => "HTTP/1.1 403 Forbidden",
404 => "HTTP/1.1 404 Not Found",
405 => "HTTP/1.1 405 Method Not Allowed",
406 => "HTTP/1.1 406 Not Acceptable",
407 => "HTTP/1.1 407 Proxy Authentication Required",
408 => "HTTP/1.1 408 Request Time-out",
409 => "HTTP/1.1 409 Conflict",
410 => "HTTP/1.1 410 Gone",
411 => "HTTP/1.1 411 Length Required",
412 => "HTTP/1.1 412 Precondition Failed",
413 => "HTTP/1.1 413 Request Entity Too Large",
414 => "HTTP/1.1 414 Request-URI Too Large",
415 => "HTTP/1.1 415 Unsupported Media Type",
416 => "HTTP/1.1 416 Requested range not satisfiable",
417 => "HTTP/1.1 417 Expectation Failed",
500 => "HTTP/1.1 500 Internal Server Error",
501 => "HTTP/1.1 501 Not Implemented",
502 => "HTTP/1.1 502 Bad Gateway",
503 => "HTTP/1.1 503 Service Unavailable",
504 => "HTTP/1.1 504 Gateway Time-out"
);
header($http[$num]);
};

//200 正常状态
header("HTTP/1.1 200 OK");

// 301 永久重定向，记得在后面要加重定向地址 Location:$url
header("HTTP/1.1 301 Moved Permanently");

// 重定向，其实就是302 暂时重定向
header("Location: http://www.xxxx.com/");

// 设置页面304 没有修改
header("HTTP/1.1 304 Not Modified");

// 显示登录框，
header("HTTP/1.1 401 Unauthorized");
header("WWW-Authenticate: Basic realm="登录信息"");
echo "显示的信息！";

// 403 禁止访问
header("HTTP/1.1 403 Forbidden");

// 404 错误
header("HTTP/1.1 404 Not Found");

// 500 服务器错误
header("HTTP/1.1 500 Internal Server Error");

// 3秒后重定向指定地址(也就是刷新到新页面与 <meta http-equiv="refresh" content="10;http://www.xxxx.com/ /> 相同)
header("Refresh: 3; url=http://www.xxxx.com/");
echo "10后跳转到http://www.xxxx.com";

// 重写 X-Powered-By 值
header("X-Powered-By: PHP/5.3.0");
header("X-Powered-By: Brain/0.6b");

//设置上下文语言
header("Content-language: en");

// 设置页面最后修改时间（多用于防缓存）
$time = time() - 60; //建议使用filetime函数来设置页面缓存时间
header("Last-Modified: ".gmdate("D, d M Y H:i:s", $time)." GMT");

// 设置内容长度
header("Content-Length: 39344");

// 设置头文件类型，可以用于流文件或者文件下载
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename="example.zip"");
header("Content-Transfer-Encoding: binary");
readfile("example.zip");//读取文件到客户端

//禁用页面缓存
header("Cache-Control: no-cache, no-store, max-age=0, must-revalidate");
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header("Pragma: no-cache");

//设置页面头信息
header("Content-Type: text/html; charset=iso-8859-1");
header("Content-Type: text/html; charset=utf-8");
header("Content-Type: text/plain");
header("Content-Type: image/jpeg");
header("Content-Type: application/zip");
header("Content-Type: application/pdf");
header("Content-Type: audio/mpeg");
header("Content-Type: application/x-shockwave-flash");
//.... 至于Content-Type 的值 可以去查查 w3c 的文档库，那里很丰富
