Why not simply define a set of variables for root dir and the other directories, and use full paths in your includes?
$root = "/wwwroot/mydomain/public/"; $homepageroot = "/"; $mydir = "subdir/"; now you can do: include $rootpath.$mydir."inc.php"; and <a href="<?php echo $hompageroot.$mydir."inc.php"; ?>">Link</a> or <a href="<?php echo $mydir."inc.php"; ?>">Link</a> Regards Michael "David Huyck" <[EMAIL PROTECTED]> schrieb im Newsbeitrag [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > I am trying to define a function that is *like* the standard PHP "include()" > function but is slightly different, but I am running into trouble with > varible scoping.
