如何从Laravel 5.2中的数据库中获取最新数据

Question

I have a database with these column :

id|company_id|company_name|create_at|updated_at|deleted_at

For example in mydatabase now, I already have 5 data. Then I just want to take 3 newest data from my database. What command should I use? Right now I'm just using

$comIn = new CompanyInfo;
$modalData = $comIn->where('company_id',$cid)->get();

$modalData contains all of the five data available, actually I can create another variable to put the last 3 data from $modalData. But I just want to do it by mysql command, Could I really do that ? What should I put in where

('company_id,$cid, bla bla bla bla bla...??)->get();
