1.方式一

namespace app\index\model;

use think\Model;

class Classfiy extends Model{
protected $table = 'classfiy';
// 方式一
public function htmllist(){
$data=$this->select();

        return $this->htmllistM($data);
    }
    public function htmllistM($data,$pid=0,$lev=''){
        static $arr=array();
        foreach($data as $key=>$value){
            if($value['pid']==$pid){
                $value['lev']=$lev;
                $arr[]=$value;
                $this->htmllistM($data,$value['id'],$lev.'!--');
            }
        }
        return $arr;
    }
// 方式二
    public function getHtmlList(&$result = [], $pid = 0, $prefx = '')
    {
     $data = $this->select();
     // $data = $this->select()->toarray();//有时出错

     foreach ($data as $value) {
         if ($value['pid'] == $pid) {
         $value['name'] = $prefx.$value['name'];
         $result[] = $value;
         $this->getHtmlList($result,$value['id'],$prefx.'|--');
     }
     }

     return $result;
        }
}

方式一返回的数据形式是
