QuestionOutputting ROW QUERY result to main program Pin

Hi,

I'm a newbie in OOP. Can you please help me how to fix this code below because it gives me an infinite output. I want to output or echo my fetched data to my main program. Thanks.

===========================================

class DB {

private $_hostdb = 'localhost';
private $_namedb = 'imsdb';
private $_userdb = 'root';
private $_passdb = '';
private $_conn;
private static $_instance;
private $_rowResult;

private function __construct(){
try{
$this->_conn=new PDO("mysql:host=$this->_hostdb;dbname=$this->_namedb",$this->_userdb,$this->_passdb);
$this->_conn->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION);
if($this->_conn){
echo "Connected Successfully!
";
}

} catch (Exception $ex) {
echo ("Connection Failed!")."
".$ex->getMessage();
}
}

public static function getInstance(){
if(!isset(self::$_instance))
{
return self::$_instance=new DB();
}
}

public function processQuery($sql){
try{

$q=$this->_conn->prepare($sql);
$q->execute();
$q->setFetchMode(PDO::FETCH_ASSOC);
return $this->_rowResult=$q->fetch(); //Is this correct??

} catch (Exception $ex) {
echo ("Failed!")."
".$ex->getMessage();
}
}
}

//MAIN PROGRAM -> OUTPUT gives me an infinite data which is wrong

$dbUser=DB::getInstance()->processQuery("SELECT * FROM users");

while($dbUser){
echo $dbUser['username'];
}
