Answer 1

Instead of using: FetchAll(PDO::FETCH_CLASS, 'classname') You can use: fetchObject('classname')

Example:

class Car extends DatabaseTable {

const TABLE_NAME = 'cars';

// Table Columns
private $color;
private $brand;
private $type;

public function __construct($pdo, $id = false)
{
    parent::__construct($pdo, TABLE_NAME, $id);
}

public static function getAll($pdo, $order = 'id') {
    $query =   'SELECT * FROM ' . self::TABLE_NAME . ' 
                ORDER BY ' . $order;

    $statement = $pdo->prepare($query);

    $objects = [];
    while ($obj = $statement->fetchObject(self::class, [$pdo])) {
        $objects[$obj->getId()] = $obj;
    }
    return $objects;
}

The parent Constructor just sets its 3 properties like: $this->id = $id;
