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：

<?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",

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
