include("common common.php");

// global variable declaration & assignment
$action = $_GET['action'];
$goto = $_GET['goto'];
$d =  new MAKEpasswd();
$d-> DB_connect();
$SQL = "SELECT * FROM filedb ORDER BY urlname DESC";

mysql_connect(MYSQL_HOST, MYSQL_USER, MYSQL_PASS);
 			//mysql_select_db(MYSQL_DB);
result = mysql_query($SQL);

found = mysql_num_rows($result);


$d->DB_close();
while ($row = mysql_fetch_array($result)) {
$urlnameArray[] = $row['urlname'];
$filenameArray[] = $row['path'];
}

?>

Two things I notice:

In common_common.php, your constuctor method (MAKEpasswd) has two arguments, $iLength, and $iChars. Those arguments are not passed when you instantiate the object in the first code block.

Also, your class ends right after "function makePassword() {...".DB_connect is not a member method, so it can't be called on the object reference.
