thinkphp Get the field name, is there a simpler way?

Thinkphp 3.2

$use=D('classone');$db=$use->select(5);$arr = $db[0] ? $db[0] : '';foreach($arr as $key => $value){       $arrKey[] =  $key;}

This, I took the name of the field to get into an array $arrKey, but I think this method is rather stupid, there should be a direct access to the method, I ask there is no???
