使用ORM关联关系,如何自己关联自己

今天碰到一个需求是需要自己关联自己,输出数据为树状,我们在定义关联关系的用get_calss方法

/*** 定义关联关系* @return \think\model\relation\HasMany*/public function user(){return $this->hasMany(get_class($this),'area','area');} {"code": 200,"message": "成功","data": [{"area": "自营","user": [{"id": 2,"usr": "毅拓科贸","area": "自营"},{"id": 3,"usr": "安博","area": "自营"},{"id": 4,"usr": "世纪扬天","area": "自营"},{"id": 5,"usr": "沧田","area": "自营"},{"id": 6,"usr": "佳阳电子","area": "自营"},{"id": 7,"usr": "博中天虹","area": "自营"},{"id": 8,"usr": "丹灵","area": "自营"},{"id": 153,"usr": "中美隆","area": "自营"},{"id": 154,"usr": "格力","area": "自营"},{"id": 155,"usr": "美承","area": "自营"}]},{"area": "安阳","user": [{"id": 9,"usr": "安阳A","area": "安阳"},{"id": 27,"usr": "安阳B","area": "安阳"},{"id": 59,"usr": "林州市","area": "安阳"},{"id": 62,"usr": "安阳县","area": "安阳"},{"id": 82,"usr": "滑 县","area": "安阳"},{"id": 113,"usr": "内黄县","area": "安阳"},{"id": 119,"usr": "汤阴县","area": "安阳"}]},

这里的get_class($this):获取的是当前类名

get_called_calss和它不同,是调用该方法的类名(和self,static和区别都是在继承上).
