Why doesn't the LIKE operator work when fetching from a collection?

Question

Laravel

We have a collection of objects, they have "slug" => "slug-ru"

$collection->where('slug', 'LIKE', 'slug')->first() // работает
$collection->where('slug', 'LIKE', 'slug%')->first() // нет
$collection->where('slug', 'LIKE', '%slug%')->first() // нет

Of course, you can also use ->whereIn( https://laravel.com/docs/5.4/collections#method-where but this is not the case.
Please tell me what I missed?

Answer 1

like database function
collection is just an array, so it can't do that.
