$typeModel = new TypeModel;

$appSiteid = 1;

$field = 'tid,cnname as name,fid,status,sort_order';

$map = [];
$map[] = ['siteid', '=', $appSiteid];

$list = $typeModel->field($field)->where($map)->order(['sort_order' => 'desc', 'tid' => 'asc'])->select();
return json_encode(['test'=>$list]);

或者直接遍历
foreach ($list as $v){
var_dump($v['name']);
die;
}

tp5在控制其中查询出的接口是对象的话，为什么不用toArray也可以当数据正常使用？
