I am working on a university project, and for my web application, I have to create a reservation system for a restaurant. My task is to implement the table reservation part. The point is that I need to ensure that when a customer makes a reservation, they can see which tables are available or how soon they will become available. It needs to be similar to choosing your seat in a cinema, where the seats are displayed, and you select which one you want. However, all of this must be done using pure PHP; no other language can be used

i don’t know how to do it.
