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\",

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
