Here, $balance is private . No external code can manipulate it directly. This protects invariants (e.g., no negative deposits). In Laravel, you see encapsulation in Eloquent models with protected $fillable or accessors/mutators.

Inheritance allows a class to adopt behavior from a parent class. Laracasts teaches you how to use the extends keyword properly, but more importantly, it introduces the critical caveat: . You will learn when inheritance makes sense (an "is-a" relationship) and when it creates rigid, brittle codebases. 3. Interfaces vs. Abstract Classes This protects invariants (e

Abstraction involves hiding complex implementation details and showing only the necessary features of an object. It helps reduce programming complexity and effort by focusing on what an object does rather than how it does it.
