Laravel getting ids of a collection without foreach

My code currently looks like this:

foreach ($things as $thing) {
            $ids[] = $thing->id;
        }
dd(Other::whereIn('thing_id', $ids)->get());

Thing model has many Other

    public function others()
    {
        return $this->hasMany(Other::class);
    }

It's working, but can I achieve this functionality without using the foreach? It doesn't seems to be clean for me. I've tried to give whole collection to where in like this:

dd(Other::whereIn('thing_id', $things)->get());

but this only returned where id was 1.

I'm looking for help to clean up this code, any help appreciated.

There is a function called "pluck"

You can apply it on a collection as following

$collection->pluck('id');

More can be seen on docs

I've already found a way to clean it up a bit, instead of foreach I can simply use :

$ids=$things->pluck('id');

If there's a cleaner way pls show me :)
