To understand the header lines you need to have some basic knowledge of the
HTTP protocol. Start eating tht HTTP RFC:
http://www.w3.org/Protocols/rfc2616/rfc2616
This will also enlighten yo about the fact that a header cannot be senz
after content has been pushed out.
This said you can use output buffering
(http://www.php.net/manual/en/function.ob-start.php) to avoid output being
sent before the headers:
Example:
ob_start();
echo "some stuff";
// we decide to redirect the client
ob_end_clean(); // clear the output buffer
header('Location: http://somewhere.com');
