thinkphp5数据的无限分类

1.方式一

<?php 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

{ "ret": 200, "data": [ { "id": 1, "name": "手机", "pid": 0, "static": 1, "time": 1588775166, "last_time": null, "delete_time": null, "lev": "" }, { "id": 4, "name": "华为手机", "pid": 1, "static": 1, "time": 1588776159, "last_time": null, "delete_time": null, "lev": "!--" }, { "id": 6, "name": "苹果手机", "pid": 1, "static": 1, "time": 1588776200, "last_time": null, "delete_time": null, "lev": "!--" }, { "id": 2, "name": "电脑", "pid": 0, "static": 0, "time": 1588775190, "last_time": null, "delete_time": null, "lev": "" }, { "id": 5, "name": "华为电脑", "pid": 2, "static": 0, "time": 1588776185, "last_time": 1588816674, "delete_time": null, "lev": "!--" }, { "id": 7, "name": "苹果电脑", "pid": 2, "static": 1, "time": 1588776215, "last_time": 1588816980, "delete_time": null, "lev": "!--" } ], "msg": "" }
