If you want to check some condition, and show an error page in case of failure, you may want to use abort_if()
short syntax. It accepts a boolean condition, and an HTTP status code to abort with.
// Don't do this:$product = Product::findOrFail($id);if($product->user_id != auth()->id()){ abort(403);}
Shorter way
// Do THIS:$product = Product::findOrFail($id);abort_if($product->user_id != auth()->id(), 403)
