PHP 使用header函数设置HTTP头的示例解析 表头

  如下所示:

  

复制代码 代码如下:

  //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: http://www.example.org/');

  //文件延迟转向:

  header('Refresh: 10; url=http://www.example.org/');

  print 'You will be redirected in 10 seconds';

  //当然,也可以使用html语法实现

  // <meta http-equiv="refresh" content="10;http://www.example.org/ />

  // 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');

  //告诉浏览器最后一次修改时间

  $time = time() - 60; // or filemtime($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';
