ThinkPHP5.1根据当前用户ID递归查询上级所有用户信息

控制器中先定义两个数组

public $data_info = [];
public $data_ids = [];

调用 时候$s1_id为当前用户的上级ID

$lists = $this->getWinfo($s1_id);//获取用户所有的上级

public function getWinfo($id,$i=''){
      
       
        if(empty($id)){
            return $this->data_info;
            
        }
        //传过来的是上级id
        $infos = Db::name('user')->where('id',$id)->find();
        if(!empty($infos)){
            $this->data_info[] = $infos;
            //出重，防止死循环
            if(!in_array($infos['s1id'],$this->data_ids)){
                $this->data_ids[] =  $infos['s1id'];
                return $this->getWinfo($infos['s1id']);
            }
        }
        return $this->data_info;
    }
