Question

I have very basic class:

class Customer {

  protected $id;
  protected $customer;

  public function __construct($customer_id) {
    $this->id = $customer_id;
    return $this->set_customer();
  }

  protected function set_customer() {
    $query = mysql_query("SELECT * FROM customer WHERE id = '$this->id'");
    $this->customer = mysql_fetch_row($query);
    return $this->customer;
  }
}

$customer = new Customer($order->customer->id);
print_r($customer);

This is not doing what I want it to but I understand why… $customer returns a reference to the Customer Object…

What I want is the MySQL row array from the mysql_fetch_row() – How do I return the array?

What am I missing?

You could leverage ArrayObject (provided you’re using PHP 5.3) to get what you want:

class Customer extends ArrayObject {

    protected $id;
    protected $customer;

    public function __construct($customer_id) {
        $this->id = $customer_id;
        $this->set_customer();
        parent::__construct($this->customer);
    }

    protected function set_customer() {
       $query = mysql_query("SELECT * FROM customer WHERE id = '$this->id'");
       $this->customer = mysql_fetch_row($query);
    }
}

Then you can use $customer as an array:

$customer = new Customer($customer_id);
echo $customer['name'];
