In the PHP language, the header () function is useful, especially when using Ajax, he will help you solve some unexpected problems. Here is some detailed explanation of header. I hope it's helpful to phper.
Copy Code code as follows:
<?php
Fix 404 Pages:
Header (' http/1.1 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 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'll be redirected in seconds ';
Could also use the HTML syntax://<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 ');
Content language (en = 中文版)
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 the content
did not get changed
Header (' http/1.1 304 not Modified ');

Header (' content-length:1234 ');
Headers for a 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, June 1997 05:00:00 GMT ');
Date in the Pastheader (' Pragma:no-cache ');
