【问题描述】：

你能帮帮我吗？我不明白如何加入 2 个或更多表，每个表都有实体。是否可以在学说中使用？我不想使用教义。

如何加入实体并在视图中使用？

class User
{
    protected $id;
    protected $email;
    protected $password;

    public function getId()
    {
        return $this->id;
    }
    public function setId($value)
    {
        $this->id = $value;
    }
    public function setEmail($value)
    {
        $this->email = $value;
    }
    public function getEmail()
    {
        return $this->email;
    }
    public function setPassword($value)
    {
        $this->password = $value;
    }
    public function getPassword()
    {
        return $this->password;
    }
}

class Info
{
    protected $id;
    protected $lastname;
    protected $firstname;

    public function getId()
    {
        return $this->id;
    }
    public function setId($value)
    {
        $this->id = $value;
    }
    public function setLastname($value)
    {
        $this->lastname = $value;
    }
    public function getLastname()
    {
        return $this->lastname;
    }
    public function setFirstname($value)
    {
        $this->firstname = $value;
    }
    public function getFirstname()
    {
        return $this->firstname;
    }
}
