// 向浏览器发送404 状态码
header(“HTTP/1.1 404 Not Found”);
或者
header(“HTTP/1.1 404″);

// 永久重定向
header(“Location: http://weizhifeng.net/”);//默认是301 跳转
// 临时重定向
header(“HTTP/1.1 302 Found”);
header(“Location: http://weizhifeng.net/”);

// 下载文件
header(“Content-type: text/plain’); // 可以替换成你需要的MIME类型
header(‘Content-Disposition: attachment; filename=”weizhifeng.txt”‘);
readfile(‘weizhifeng.txt’);

其他的头信息可以参考HTTP/1.1 specification
如果在header之前已经有了输出,那么请使用ob_start()函数。
