Zf2实体加入

Question

你能帮我吗？我无法理解如何连接2个以上的表格，每个表格都有实体。在教条中是否可以使用？我不想使用教条。

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; 
    } 
}
