　　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');
