Laravel update record control

Question

I'm building a laravel application where i have a Reservation model. After the new record is created, the user may want to update it.

I'm looking for a solution to check if the UpdateRequest values are the same of the actual records and if there are updates only update the modified values.

Example, the original record has :

{'id' => 1, 'name' = 'Jhon', surname = 'Doe'}

While the UpdateRequest has

{'id' => 1, 'name' = 'Jhon', surname = 'Kirby'}

So, my questions are :

• How do i check which values are different?
• How do i update only the specified values?

I've tried to look at the documentation of laravel but it doesn't seem to refer to this situation, is there any solution or should I just update all the values?

Thank you
