Laravel check if collection is empty

To determine if there are any results you can do any of the following:

if ($mentor->first()) { } if (!$mentor->isEmpty()) { }if ($mentor->count()) { }if (count($mentor)) { }if ($mentor->isNotEmpty()) { }

Notes / References

->first()

https://laravel.com/api/5.7/Illuminate/Database/Eloquent/Collection.html#method_first

isEmpty() https://laravel.com/api/5.7/Illuminate/Database/Eloquent/Collection.html#method_isEmpty

->count()

https://laravel.com/api/5.7/Illuminate/Database/Eloquent/Collection.html#method_count

count($mentors) works because the Collection implements Countable and an internal count() method:

https://laravel.com/api/5.7/Illuminate/Database/Eloquent/Collection.html#method_count

isNotEmpty()

https://laravel.com/docs/5.7/collections#method-isnotempty

So what you can do is :

if (!$mentors->intern->employee->isEmpty()) { }

You can always count the collection. For example $mentor->intern->count() will return how many intern does a mentor have.

https://laravel.com/docs/5.2/collections#method-count

In your code you can do something like this

foreach($mentors as $mentor)    @if($mentor->intern->count() > 0)    @foreach($mentor->intern as $intern)        <tr class="table-row-link" data-href="/werknemer/{!! $intern->employee->EmployeeId !!}">            <td>{{ $intern->employee->FirstName }}</td>            <td>{{  $intern->employee->LastName }}</td>        </tr>    @endforeach    @else        Mentor don't have any intern    @endif@endforeach

Starting from Laravel 5.3 you can simply use :

if ($mentor->isNotEmpty()) {//do something.}
