If statements in blade templating?

I have an empty set of data, in my blade template I check for this via:

@if(empty($data))
   It's empty!
@else
   @foreach($data as $asset)
      $asset->alt
   @endforeach
@endif

The problem is, I get the error:

Trying to get property of non-object

But this should not even happen as the else of the if statement should not even run. Why is this happening?

I've checked and 'It's empty' is displayed.

You can use 

@if(count($data))
   @foreach($data as $asset)
      {{$asset->alt}}
   @endforeach
@else
   It's empty!
@endif

You could compare $data against null

if ($data == null)
{
   echo "It's empty!";
}
else
{
   foreach ($data as $asset)
   {
      echo $asset->alt;
   }
}

The if-empty block only checks if $data is empty, it does not ensure that the items in the array are actual objects.

Take this PHP code as an example:

$data = [1, 2, 3];

if (empty($data))
{
   echo "It's empty!";
}
else
{
   foreach ($data as $asset)
   {
      echo $asset->alt;
   }
}

The above code will throw the same error, since 1, 2 and 3 are not objects.
