Aggregate functions are available in same way in Laravel eloquent as they were with Laravel query builder. Here is an example of count() method.
$countVips = Contact::where( 'vip', true )->count();
We can also use sum functions.
$sumVotes = Contact::sum('votes');
Another method is average which is used as avg().
$avgSkills = Contact::avg( 'skill_level' );
That is all for aggregate methods. If you have any question please leave a comment. We really appreciate that.
