How is the principle of hidden responsibilities and their automatic processing implemented in Laravel?

In Laravel, the principle of convention over configuration is implemented through the mechanism of events and listeners, as well as through service providers and facades, which automatically handle certain tasks without explicit calls in the code.

For example, Eloquent models automatically handle lifecycle events (creation, updating, deletion) through handler methods (boot, creating, updating, etc.), allowing automatic validation, logging, or other actions without explicit invocation.

Laravel also uses service providers for automatic registration of dependencies and configurations during application startup, hiding details and simplifying the developer's work.

Example: when saving a model, you can define an event handler method that will automatically execute:

class User extends Model {
    protected static function boot() {
        parent::boot();

        static::creating(function ($user) {
            // Automatically hash the password before saving
            $user->password = bcrypt($user->password);
        });
    }
}

Thus, Laravel hides implementation details and automatically handles tasks, making development easier and keeping the code clean.
