What is Route Model Binding in Laravel?

Route Model Binding automatically injects model instances into route handlers based on route parameters. Instead of manually fetching a model: $user = User::findOrFail($id), type-hint the model in the controller method: public function show(User $user). Laravel automatically resolves the User model by matching the route parameter ({user}) to the model's primary key. If no record exists, a 404 response is returned automatically. You can customize the resolution column: Route::get("/users/{user:slug}", ...) resolves by the slug column. Custom resolution logic can be added in the model's resolveRouteBinding() method. This eliminates repetitive findOrFail boilerplate.
