Try searching the forums for the words "cannot modify header information".

I added the ob_start(); and it works fine.

I'm not really sure how this statement works though.

Really?

From [man]header[/man]:

Remember that header() must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP. It is a very common error to read code with include(), or require(), functions, or another file access function, and have spaces or empty lines that are output before header() is called. The same problem exists when using a single PHP/HTML file.
<html>
<?php
/* This will give an error. Note the output
 * above, which is before the header() call */
header('Location: http://www.example.com/');
?>  

And, as far as:

I'm not really sure how this statement works though.
