Collection count in Laravel

Can I use count($posts) in Laravel to retrieve the number of elements in a collection, and how does it differ from $posts->count()?

Thank you

In short it depend of the Laravel version you're using. on laravel 5.5 for example i see the Collection class implement the countable interface so you could call count($posts) but version 8 of laravel don't anymore implement it so you couldn't with this version. Anyway you would get the same result using both function

UPDATE: as mentionned by @apokryfos the Collection class implement Enumerable so there is no difference and you can use both.

->get()->count() will load Eloquent model objects into memory and then will count those.

->count() will use DB aggregate function

simple php count(Model::all()) will also count the model objects already loaded which is not necessary
