    In the function below, before I open the directory I first test to
    make sure the address I have is, in fact, a directory. This function
    was working fine on one web server running FreeBSD and PHP 4.06.
    However, today I'm trying to run this software on a new server (RH
    Linux 9, PHP 4.2.3) and the directory is failing the is_dir() test.
    The error message that I have in my code is printing out this error:

    In getListOfAnyDirectory(), we expected the function to be handed an
    address to a directory, but instead we were given this:
    ppArrangementsPublic/.

    Now, ppArrangementsPublic/ looks like a directory to me. So why is it
    failing the test?

    function getListOfAnyDirectory($address=false) {
            // 03-17-04 - this function should be given an address to a folder.

            $controllerForAll = & getController();
            $resultsObject = & $controllerForAll->getObject("McResults", " in
    getListOfAnyDirectory().");
            $theDirFilesArray = array() ;
            
            $address2 = str_replace("/", "", $address);

            if (is_dir($address) || is_dir($address2)) {
                    // open the directory and load all the files into an array
                    $theDir = @ opendir($address);
                    
                    if ($theDir) {
                            // We go through the array one element at a time, putting it into a
    new array, minus invisible files
                            //marked by "." and ".."
                            
                            while ($theDirFiles = readdir ($theDir)) {
                                    if ($theDirFiles != "." && $theDirFiles != "..") {
                                            $theDirFilesArray[] = $theDirFiles ;
                                    }
                            }
                            
                            closedir ($theDir) ;
                            return $theDirFilesArray;
                    } else {
                            $resultsObject->error("In getListOfAnyDirectory(), we tried to open
    the directory at the address $address, but for some reason it didn't
    open.", "getListOfAnyDirectory");
                    }
            } else {
                    $resultsObject->error("In getListOfAnyDirectory(), we expected the
    function to be handed an address to a directory, but instead we were
    given this: $address.", "getListOfAnyDirectory");
            }
    }
