这篇文章主要介绍了php中header使用的http协议及常用方法,包含了各种错误编码类型及其含义,需要的朋友可以参考下
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：
复制代码 代码如下:
function https($num) {
$http = array (
100 => http/1.1 100 continue,
101 => http/1.1 101 switching protocols,
200 => http/1.1 200 ok,
201 => http/1.1 201 created,
202 => http/1.1 202 accepted,
203 => http/1.1 203 non-authoritative information,
204 => http/1.1 204 no content,
205 => http/1.1 205 reset content,
206 => http/1.1 206 partial content,
300 => http/1.1 300 multiple choices,
301 => http/1.1 301 moved permanently,
302 => http/1.1 302 found,
303 => http/1.1 303 see other,
304 => http/1.1 304 not modified,
305 => http/1.1 305 use proxy,
307 => http/1.1 307 temporary redirect,
400 => http/1.1 400 bad request,
401 => http/1.1 401 unauthorized,
402 => http/1.1 402 payment required,
403 => http/1.1 403 forbidden,
404 => http/1.1 404 not found,
405 => http/1.1 405 method not allowed,
406 => http/1.1 406 not acceptable,
407 => http/1.1 407 proxy authentication required,
408 => http/1.1 408 request time-out,
409 => http/1.1 409 conflict,
410 => http/1.1 410 gone,
411 => http/1.1 411 length required,
412 => http/1.1 412 precondition failed,
413 => http/1.1 413 request entity too large,
414 => http/1.1 414 request-uri too large,
415 => http/1.1 415 unsupported media type,
416 => http/1.1 416 requested range not satisfiable,
417 => http/1.1 417 expectation failed,
500 => http/1.1 500 internal server error,
501 => http/1.1 501 not implemented,
502 => http/1.1 502 bad gateway,
503 => http/1.1 503 service unavailable,
504 => http/1.1 504 gateway time-out
);
header($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: ');
// 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 相同)
header('refresh: 3; url=http://www.xxxx.com/');
echo '10后跳转到';
// 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
