Need to check if an object is empty in laravel

If it is a Eloquent Collection as it appears to be from your example you can use the isEmpty collection helper function;

@if(!$contacts->isEmpty())
//display contacts
@else
You dont have contacts
@endif

Collections Documentation

There are few ways:

if (!empty($contacts))

if (!contacts->isEmpty())

if (count($contacts) > 0)

if ($contacts->count() > 0)

Your Eloquent query returns an array of result, so you can use count.

@if(count($contacts) > 0)
//Display contacts
@else
//No contacts
@endif
