用于演示PHP header()函数用法的代码，介绍了refresh方法，老外写的，当然不会太差，有需要的朋友参考下吧。

php header头信息的例子。

<?php // fix 404 pages: header('HTTP/1.1 200 OK');  
// set 404 header: header('HTTP/1.1 404 Not Found');  
// set Moved Permanently header (good for redrictions) 
// use with location header header('HTTP/1.1 301 Moved Permanently');
  // redirect to a new location: header('Location: http://www.example.org/');  
// redrict with delay: header('Refresh: 10; url=http://www.example.org/'); print 'You will be redirected in 10 seconds';  
// you could also use the HTML syntax:// <meta http-equiv="refresh" content="10;http://www.jbxue.com/ /> 
 // override X-Powered-By: PHP: header('X-Powered-By: PHP/4.4.0'); header('X-Powered-By: Brain/0.6b'); 
 // content language (en = English) header('Content-language: en');  
// last modified (good for caching) $time = time() – 60; 
// or filemtime($fn), etc header('Last-Modified: '.gmdate('D, d M Y H:i:s', $time).' GMT');  
// header for telling the browser that the content // did not get changed header('HTTP/1.1 304 Not Modified');
  // set content length (good for caching): header('Content-Length: 1234'); 
 // Headers for an download: 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'); 
// Disable caching of the current document: 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 pastheader('Pragma: no-cache');
 // set content type: header('Content-Type: text/html; charset=iso-8859-1');
 header('Content-Type: text/html; charset=utf-8'); header('Content-Type: text/plain');  
// plain text file header('Content-Type: image/jpeg'); 
 // JPG picture header('Content-Type: application/zip');
