Thanks Chris
Thats what I was after :)
At the top of each page I now do
$reltoroot = preg_replace("|/[^/]+|", "../", dirname($_SERVER['PHP_SELF']));
ini_set ("include_path",ini_get("include_path").":".$reltoroot."../include");
which takes care of the include path
I use the path translated info for pages that are sym linked across virtual
domains such as admin pages.
Thanks again
Tom
