Try changing 

class connection {
  protected $db_connect;
  public $db_username = 'root';
  public $db_hostname = 'localhost';
  public $db_database = 'test';
  public $db_password = '';

to


class connection {
  protected $db_connect;
  public $db_username = "root";
  public $db_hostname = "localhost";
  public $db_database = "test";
  public $db_password = "";

Also, I usually work via DAO

class DAO {
	private static $dbHost = "localhost";
	private static $dbName = "kcart";
	private static $dbUser = "kcartTest";
	private static $dbPass = "";
	private static $sharedPDO;

	protected $pdo;

	function __construct() {
		if(empty(self::$sharedPDO)) {
			self::$sharedPDO = new PDO("mysql:host=" . self::$dbHost . ";dbname=" . self::$dbName, self::$dbUser, self::$dbPass);
			self::$sharedPDO->exec("SET CHARACTER SET utf8");
			self::$sharedPDO->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
			self::$sharedPDO->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
		}
		$this->pdo =& self::$sharedPDO;
	}

Also I believe this:

$this->connection = new PDO("mysql:host=$this->db_hostname;$this->db_database", $this->db_username, $this->db_password);

Is invalid, you need to specify that 

$this->db_datebase

is the database name:

$this->connection = new PDO("mysql:host=$this->db_hostname;dbname=$this->db_database", $this->db_username, $this->db_password);

Might be wrong though

Yes, but it still wont print the debug_Connection() function..

I missed the dbname= in the PDO(), now it also gives me error IF the DB wont exists, but doesnt give me a connection succeed message when I try to print it.

 

I'm not really sure what you mean, if should return an error if the database table doesn't exist. Why would it give a connection success message when it didn't successfully connect?

If you're getting an error stating that the db table doesn't exist then double check your table name is correct

No, no and no.

First I was unable to get the error even with false details, now it gives me the error I want when false details.

But still wont print my debug function.

From the snippet you've shown you're not even calling the 

debug_Connection()

function?
