A summary of the HTTP protocol and common methods used by Headers in PHP, a summary of headers

The examples in this article summarize the HTTP protocol and common methods used by Header in PHP. Share it with everyone for your reference. The specific method is as follows:

Copy code The code is as follows:

function https($num) {
$http = array (
100 => "HTTP/1.1 100 Continue",

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 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
