Is there a simpler way for thinkPHP to get the field name?

Thinkphp3.2 {code ...} in this case, I get the field name into an array $ arrKey, but I think this method is stupid and there should be a direct way to get it. is there any ??? Thinkphp 3.2

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

In this case, I get the field name into an array $ arrKey, but I think this method is stupid and there should be a direct way to get it. is there any ???
