    Same function with some minor changes and comments added

    FTP function checks if a directory exists

    <?php
    function ftp_is_dir( $dir ) {
        global     $ftpcon;
            // get current directory
            $original_directory = ftp_pwd( $ftpcon );
            // test if you can change directory to $dir
        // suppress errors in case $dir is not a file or not a directory
            if ( @ftp_chdir( $ftpcon, $dir ) ) {
                // If it is a directory, then change the directory back to the original directory
                ftp_chdir( $ftpcon, $original_directory );
            return     true;
        }
        else {
            return     false;
        }       
    }
    ?>

    Works like the other functions in this page's notes, but this one doesn't make use of a global FTP connection, so it takes parameters like the other functions in the extension

    <?php
    function ftp_directory_exists($ftp, $dir)
    {
            // Get the current working directory
            $origin = ftp_pwd($ftp);
       
            // Attempt to change directory, suppress errors
            if (@ftp_chdir($ftp, $dir))
        {
                // If the directory exists, set back to origin
                ftp_chdir($ftp, $origin);   
            return     true;
        }

            // Directory does not exist
            return false;
    }
    ?>
