First you should know what http headers are. All you need to know about
php's header() is that if you want to send specific headers, other than
what the server sends by default, you use header to set them. Here's a
good page to start with: http://www.cs.tut.fi/~jkorpela/http.html
For example, here's what Google sends, when you open the index page:
HTTP/1.x 200 OK
Cache-Control: private
Content-Type: text/html; charset=UTF-8
Content-Encoding: gzip
Server: GWS/2.1
Content-Length: 1731
Date: Fri, 01 Jun 2007 12:50:35 GMT
It's just basic info for the browser, what charset the browser should
use to display the page (utf-8), how it should render it (html), how big
file it is...
You can do plenty of useful things with headers, Google is your friend.
