Laravel collection filtering to avoid null records

Question

is there an inbuilt way to loop through collections and return only the objects that are meeting a specific condition?

like skip all records that has $user->role === null

Answer 1

You can use filter method to filter the users against your condition

$filteredUsers = $users->filter(function ($user, $key) {
    return $user->role != null;
});

Answer 2

You actually don't even need the ->filter method if you're using Eloquent. If role is a relationship of your User model, you can simply call:

$users = User::has("role")->get();

This will automatically return only Users that have a role, or where $user->role is not null.
