本文實例總結了PHP中Header使用的HTTP協議及常用方法。分享給大家供大家參考。具體方法如下：
復制代碼 代碼如下:<?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",

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",

503 => "HTTP/1.1 503 Service Unavailable",
504 => "HTTP/1.1 504 Gateway Time-out"
);
header($http[$num]);
};
//200 正常狀態
header('HTTP/1.1 200 OK');
// 301 永久重定向，記得在後面要加重定向地址 Location:$url
header('HTTP/1.1 301 Moved Permanently');
// 重定向，其實就是302 暫時重定向
header('Location: http://www.xxxx.com/');
// 設置頁面304 沒有修改
header('HTTP/1.1 304 Not Modified');
// 顯示登錄框，
header('HTTP/1.1 401 Unauthorized');
header('WWW-Authenticate: Basic realm="登錄信息"');
echo '顯示的信息！';
// 403 禁止訪問
header('HTTP/1.1 403 Forbidden');
// 404 錯誤
header('HTTP/1.1 404 Not Found');
// 500 服務器錯誤
header('HTTP/1.1 500 Internal Server Error');
// 3秒後重定向指定地址(也就是刷新到新頁面與 <meta http-equiv="refresh" content="10;http://www.xxxx.com/ /> 相同)
header('Refresh: 3; url=http://www.xxxx.com/');
echo '10後跳轉到http://www.xxxx.com';
// 重寫 X-Powered-By 值
header('X-Powered-By: PHP/5.3.0');
header('X-Powered-By: Brain/0.6b');
//設置上下文語言
header('Content-language: en');
// 設置頁面最後修改時間（多用於防緩存）
$time = time() - 60; //建議使用filetime函數來設置頁面緩存時間
header('Last-Modified: '.gmdate('D, d M Y H:i:s', $time).' GMT');
// 設置內容長度
header('Content-Length: 39344');
// 設置頭文件類型，可以用於流文件或者文件下載
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="example.zip"');
header('Content-Transfer-Encoding: binary');
readfile('example.zip');//讀取文件到客戶端
//禁用頁面緩存
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');
//設置頁面頭信息
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');
//.... 至於Content-Type 的值 可以去查查 w3c 的文檔庫，那裡很豐富
