multiple domain pointing to their ows folder of the same hotsting

Hi,

I have 2 domains but 1 hosting for the 2. ( same dns settings for the 2
domains )

www.xxx.be and www.yyy.be ( for exemple )

i'd like www.xxx.be pointing to www.xxx.be/xxx and www.yyy.be pointing to
www.yyy.be/yyy

Do you have an exemple how to do this using a simple index.php in the root
directory of my web hosting, or a javascript that can do the job ?

Thanks for your help.
