index.html to index.php ???

Rustin, after reading this thread again I realized you did mention "Domain." Sorry about that.

All good! thanks again!

RewriteRule ^(.*).html $1.php [L]

This is good solution, but IMO better will be add to your .htaccess file this code
AddHandler application/x-httpd-php .php .phtml .htm

which forces server parse PHP code contained in files with extension htm.

Thanks Vlado,
So I could just add my php script to my html pages and leave the extention the same here too as well and the .html would work like a .php?
I'll try it...!

Add the whole line:
AddHandler application/x-httpd-php .php .phtml .htm

Would it work adding more to it?
AddHandler application/x-httpd-php .php .phtml .htm .html .shtml

Yes, it should.
