二维数组排序精简代码
//楼栋列表
$buildesTemp = db('room')->field('buildingno')->where('v_id','eq', $v['id'])->group('buildingno')->select();
//排序
$timeKey = array_column( $buildesTemp, 'buildingno');
array_multisort($timeKey, SORT_ASC, $buildesTemp);//楼栋列表
$buildesTemp = db('room')->field('buildingno')->where('v_id','eq', $v['id'])->group('buildingno')->select();
//排序
$timeKey = array_column( $buildesTemp, 'buildingno');
array_multisort($timeKey, SORT_ASC, $buildesTemp);
