How about additional get_used_packages_absolute() or | conditional parameter like get_used_packages($relative=0)? Just to make this clear: "use" is specifically intended for loading PEAR packages. It is not a generic replacement for include() or require(), it has a very specific purpose. Even relative paths is wrong in this context. Actually, relative paths are _more_ wrong than absolute paths, because you have to change it if you move the file to another directory. PEAR packages are supposed to be installed in one or more designated directories that appear in your include path. The only special check "use" needs is testing whether the first character of its parameter is "." or "/", to avoid that people try using it for stuff that include() and require() are better suited for. - Stig
