Php 一对多/多对一原则。不起作用

几天来，我一直在努力解决这个问题，但运气不佳

首先是一些澄清：

基本上，我想在“用户”和“商店”之间建立关系，我的计划是识别特定用户最喜欢的商店，并且从商店的角度来看，在一个特定商店中购物的人是他们最喜欢的商店。 我的猜测是使用多人关系，但在查找了相关示例后，许多网站描述，如果您需要多人关系和其他字段（在我的例子中，我有3个附加字段），则必须使用一人/多人关系

我在数据库中使用SQLITE只是为了开发，我在PHP中使用Slim框架编写RESTAPI

当使用这样的方法获取特定实体时，一切都正常工作

/**
     * Fetching user by email
     * @param String $email User email
     */
    public function getUserByEmail($email) {
    $user = $this->getEntityManager()->getRepository('User')
                                     ->findOneBy(array('email' => $email));
    if ($user === null) {
        return null;
    } else {
        return $user;
    }
}

或

或

一旦我得到任何实体，我就可以读取它们的属性。除非我试图获得以下信息：

echo $User->getShopsAt(); i get an error saying "Object of class Doctrine\ORM\PersistentCollection could not be converted to string"

如果我尝试

echo [$User->getShopsAt()]; i get "Array" as reponse

echo count([$User->getShopsAt()]); i get 1

如果我尝试

echo [$User->getShopsAt()]; i get "Array" as reponse

echo count([$User->getShopsAt()]); i get 1

如果我理解，对getShopsAt（）的调用应该返回与用户id匹配的“UserStore”实体的所有实例，但我无法访问其任何属性。 我尝试过的一切都失败了，我还想指出，我使用了用户Id“1”，在“UserStore”表中有2个条目。那么，为什么计数返回1。

我使用YML格式创建了3模式，因为我发现它比PHP更清晰

通过这些模式，我使用命令“vendor/bin/orm:generate entities./src”创建了实体（请参见底部的结果实体）

然后，我使用vendor/bin/orm:schema工具：update--force创建数据库模式（请参见底部的数据库SQL和数据）

之后，我在Chrome浏览器上使用升级的REST客户端扩展在数据库上创建了一些数据。但我已经独立创建了所有这些。这意味着，首先创建用户而不将任何内容设置为shopsAt属性，然后创建一些商店而不将任何内容设置为Shopsers属性，然后创建一些UserStores

重要问题： 在创建UserStore的过程中，我必须恢复实际的用户和Store，以设置其关系的反向端

或

不，仅仅向UserStore添加正确的密钥和条令将在读取用户/存储时进行匹配，因为UserStore的创建就足够了，因为它是关系的拥有方

或

我必须手动修改由orm:generate entities命令自动生成的实体，并在UserStore的setStore和setUser方法中更新反转侧？如上所述

我的数据库如下所示：

这将把UserStore对象的ArrayCollection转换为UserStore对象的简单数组。

调试的快速提示：尝试

dump（$value）而不是
echo$value
。谢谢Tomás。您的评论很有用，dump不起作用，但我遵循您的想法，在PHP文档中找到了var_dump。使用它之后，它显示了一个几乎不可能理解的巨大结构，但是我能够看到关系中使用的所有字段，并且我发现了错误。在我的YML文件中，用户被设置为mappedBy:product，应该是mappedBy:User。再次感谢，抱歉这是
var\u dump（$value）当然。dump是我使用的调试工具的自定义函数。不管怎样，我很高兴它对你有帮助。
