Laravel check if collection is empty

laravel array to collection
laravel collection
eloquent collection
laravel unique = $collection
call to a member function isempty() on null
check if collection is empty java
contains laravel
laravel push

I've got this in my Laravel webapp:

@foreach($mentors as $mentor)
    @foreach($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
@endforeach

How could I check if there are any $mentors->intern->employee ?

When I do :

@if(count($mentors))

It does not check for that.

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

->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:

isNotEmpty()
