What are some examples of model binding in Laravel?

Model binding in Laravel allows you to automatically inject model instances into your routes. For example, if you have a route like Route::get('/user/{user}', 'UserController@show');, Laravel will automatically fetch the User model instance that matches the ID in the URL.

Can you give me a more detailed example?

Sure! Let's say you have a Post model. You can define a route like Route::get('/post/{post}', 'PostController@show');. When a user accesses /post/1, Laravel will automatically retrieve the Post model with an ID of 1 and pass it to the show method of the PostController.

What if the model doesn't exist?

If the model doesn't exist, Laravel will automatically return a 404 response. This is a built-in feature of model binding that helps manage errors gracefully.

Are there any other types of binding?

Yes, Laravel also supports route model binding with custom keys and even binding multiple models in a single route.
