dd（）读取var_dump（）无法读取的值

Question

In one of my controllers I call a view with the variable $members:

$members = Member::orderBy("created_at", "desc")->get();

Then in the view I loop over all the member's groups:

@foreach ($members as $group)
    <?php $group = $group->group(); ?>
    <b>{{ $group->title }}</b> // fails
@endforeach

This throws a Trying to get property of non-object exception. If I do

@foreach ($member as $group)
    <?php $group = $group->group(); ?>
    <?php dd($group); ?>       // works
    <b>{{ $group->title }}</b> // fails
@endforeach

I can see all the attributes array populated with all the values I want. Why can dd() read values I can't read using {{ $var }}?

---

@foreach ($member as $group)
    <?php $group = $group->group(); ?>
    <?php var_dump($group); ?> // fails
    <b>{{ $group->title }}</b> // fails
@endforeach

fails as well.

Answer 1

I think I found the error. For some reason I cannot read $group->value, but $group["value"] works. It may be that group is a keyword.
