如何使用PDO的FETCH_CLASS分配构造函数参数？

Question

I want to create instances of objects using PDO. I know that there's plently of questions already but I have only found that it is possible to send an array of paramters to a constructor. To me it seems that the constructor can only accept an array as argument. However this would make the constructor less meaningful.

I want to create a class with my own getters and setters like this:

class MyClass {
    private propertyA
    private propertyB

    public __constructor($argA, $argB) {
        $this->setPropertyA($argA);
        $this->setPropertyB($argB);
    }

    public setPropertyA($arg) {
        $this->proprtyA = $arg;
    }
}

Is there an elgant way to create an instance of such a class using data from a database, preferably using PDO.

Freeballin' here:

$handle = new PDO("blahblahblah");
$statement = $handle->prepare("SELECT blahblah");
$statement->execute();
$object_params = $statement->fetch(PDO::FETCH_ASSOC);

$object = new Object($object_params);
// OR...
$object = new Object($object_params["col_1"], $object_params["col_2"], "etc.");

Alternatively:

class MyClass {
    private propertyA
    private propertyB

    public __constructor() {
        $handle = new PDO("blahblahblah");
        $statement = $handle->prepare("SELECT blahblah");
        $statement->execute();
        $object_params = $statement->fetch(PDO::FETCH_ASSOC);

        $this->setPropertyA($object_params[$argA_key]);
        $this->setPropertyB($object_params[$argB_key]);
    }

    public setPropertyA($arg) {
        $this->proprtyA = $arg;
    }
}

I don't know what you're looking for exactly. Could you comment?
