Php 带对象的原则与DQL

我学习符号和教义。我有表格：用户、产品和付款。我想把所有的关系都整理好。例如：细枝中的product.getPackagesId.name

User: ID, NAME etc.
products: ID, USER_ID(relationships), PACKAGES_ID(relationships)...
payments: ID,  PRODUCTS_ID(relationships)...

现在：我有id user（getID（）），想要获得产品，但在我遇到付款问题之后

    $em = $this->getDoctrine()->getEntityManager();
    $connection = $em->getConnection();
    $statement = $connection->prepare("SELECT * FROM `products` JOIN payments ON products.id=payments.products_id where products.user_id=:user");
    $statement->bindValue('user', $userID);
    $statement->execute();
    $products = $statement->fetchAll();


[0] => Array //name table
    (
        [id] => 3 //products
        [user_id] => 1 //products
        [packages_id] => 1 //products
        [status] => 0 //products
        [mail] =>  //products
        [data_trial] =>  //payments
        [products_id] => 3 //payments
        [data_order] => 2014-08-05 14:07:49 //payments
        [data_payment] => //payments
        [data_billing] => 30 //payments
        [data_expiration] =>  //payments
    )

我有所有的记录。这很好，但我有包裹，这不是教义中的目标。我不能利用人际关系。我尝试了createQuery，但返回了2个对象（用于产品和付款）

返回：

[0] => Array
    (
        [id] => 3
        [status] => 
        [mail] => 
    )

[1] => Array
    (
        [id] => 3
        [data_order] => DateTime Object
            (
                [date] => 2014-08-05 14:07:49.000000
                [timezone_type] => 3
                [timezone] => Europe/Warsaw
            )

        [data_payment] => 
        [data_billing] => 30
        [data_expiration] => 
    )

您没有使用DQL，而是直接使用SQL，因为您使用的是原则DBAL而不是原则ORM。我不确定ORM是否可以做你想做的事情，但是你可以看看数组的特性：Ok。我编辑了这篇文章。我添加了DQL。返回2个对象的错误在哪里？我认为这是因为您显式地选择了它们“从中选择p，c…”。请记住，这不是SQL。它应该类似于“从MySaleBundle中选择p:Products p JOIN p.payments pa WHERE p.user_id=：id”。但是，我仍然不确定信条是否能帮你得到报酬。看：否则。用法：getResult（Query:：HYDRATE\u SCALAR）我的前缀中有1个对象：[p\u id]=>3，[c\u data\u payment]等等。但是如何在twig中使用product.getPackagesId.name？product.p_getPackagesId.name不起作用。

[0] => Array
    (
        [id] => 3
        [status] => 
        [mail] => 
    )

[1] => Array
    (
        [id] => 3
        [data_order] => DateTime Object
            (
                [date] => 2014-08-05 14:07:49.000000
                [timezone_type] => 3
                [timezone] => Europe/Warsaw
            )

        [data_payment] => 
        [data_billing] => 30
        [data_expiration] => 
    )
