Domainname re-direct or target?

[bevanleeuw]

Hi all

I have a website running for a while.
Lets say this website has domain (domain-a dot be)

Now i registerd a few more domains which are related to the website content.

What is the best thing to do?
1) Redirecting the domeinname to the main website by uploading a php script.

 <?php
Header( "HTTP/1.1 301 Moved Permanently" );
Header( "Location: (domain-a dot be)" );
?>

2. OR, Target the domains folder in Hosting Space to the main website folder in Hosting Space. like \domain-a dot be\wwwroot

I need advice which is the best for SEO.

I'm new in SEO so everything is welcome.

It makes no difference, none of this will help or hurt your SEO in any way.
