php中利用header设置content-type和常见文件类型的content-type

 

在php中可以通过header函数来发送头信息，还可以设置文件的content-type，下面整理了一些常见文件类型对于的content-type值。

 

//author https://www.lai18.com 
//date 2015-06-22
//定义编码
header( 'content-type:text/html;charset=utf-8 ');

//atom
header('content-type: application/atom+xml');

//css
header('content-type: text/css');

//javascript
header('content-type: text/javascript');

//jpeg image
header('content-type: image/jpeg');

//json
header('content-type: application/json');

//pdf
header('content-type: application/pdf');

//rss
header('content-type: application/rss+xml; charset=iso-8859-1');

//text (plain)
header('content-type: text/plain');

//xml
header('content-type: text/xml');

// ok
header('http/1.1 200 ok');

//设置一个404头:
header('http/1.1 404 not found');

//设置地址被永久的重定向
header('http/1.1 301 moved permanently');

//转到一个新地址
header('location: https://www.example.org/'); 
//文件延迟转向:
header('refresh: 10; url=https://www.example.org/');
print 'you will be redirected in 10 seconds';

//当然，也可以使用html语法实现
// 

// override x-powered-by: php: header('x-powered-by: php/4.4.0'); header('x-powered-by: brain/0.6b'); //文档语言 header('content-language: en'); //告诉最后一次修改时间 $time = time() - 60; // or filemtime($fn), etc header('last-modified: '.gmdate('d, d m y h:i:s', $time).' gmt'); //告诉浏览器文档内容没有发生改变 header('http/1.1 304 not modified'); //设置内容长度 header('content-length: 1234'); //设置为一个下载类型 header('content-type: application/octet-stream'); header('content-disposition: attachment; filename=example.zip'); header('content-transfer-encoding: binary'); // load the file to send: readfile('example.zip'); // 对当前文档禁用缓存 header('cache-control: no-cache, no-store, max-age=0, must-revalidate'); header('expires: mon, 26 jul 1997 05:00:00 gmt'); // date in the past header('pragma: no-cache'); //设置内容类型: header('content-type: text/html; charset=iso-8859-1'); header('content-type: text/html; charset=utf-8'); header('content-type: text/plain'); //纯文本格式 header('content-type: image/jpeg'); //jpg*** header('content-type: application/zip'); // zip文件 header('content-type: application/pdf'); // pdf文件 header('content-type: audio/mpeg'); // 音频文件 header('content-type: application/x-shockw**e-flash'); //flash动画 //显示登陆对话框 header('http/1.1 401 unauthorized'); header('www-authenticate: basic realm=top secret'); print 'text that will be displayed if the user hits cancel or '; print 'enters wrong login data';
