I am currently going to build a simple booking website for a restaurant using PHP which will have two major functionality. One will be to book for seats and other to possibly let people order takeaways. Now that will be the front end of the system. But I will need something for the owners of the restaurant to know the bookings and the order. I know there is some content management systems like Joomla and Drupal but I am thinking if there is some other way to provide a simple back-end. If anyone could point me some resources or give me some idea on this I would be grateful. Thank you.
