Laravel check if collection is empty

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.

In blade, you can use isNotEmpty() or isEmpty() but, as always with blade, you must start with @.

@if($collection->isNotEmpty())
    <ul>
        @foreach($collection as $item)
            //normal loop
        @endforeach
    </ul>
@else
    <p>No items found.</p>
@endif

First you can convert your collection to an array. Next run an empty method like this:

if(empty($collect->toArray())){}

This is the best solution I found so far.

in blade

@if($mentors->count() == 0)
    <td colspan="5" class="text-center">
        Nothing Found
    </td>
@endif

in controller

if ($mentors->count() == 0) {
    return "Nothing Found";
}

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()) { }

I prefer

(!$mentor)

Is more effective and accurate

Starting from Laravel 5.3 you can simply use :

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

This is the fastest way: 

if ($coll->isEmpty()) {...}

Other solutions like count do a bit more than you need which costs slightly more time.

Plus, the isEmpty() name quite precisely describes what you want to check there so your code will be more readable.

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
