PHP for the Web is a terrific introduction on how to use modern PHP effectively. While there is a lot of material out there about building applications with PHP, most of them focus on using a framework like Laravel or Symfony. By working with pure PHP, you will be able to focus on the core ideas instead of how a particular framework implements them.

In this course, you will learn how to use multiple web technologies like POST requests, forms, sessions, and redirects to build a CRUD application with an authentication system.

By the end, you will have all the ingredients at your disposal to go out and build stunning, dynamic PHP web applications.

PHP for the Web: Learn PHP without a Framework

# Giving a unique identifier to each tour
We have successfully built a form that enables the user to add a tour to the list of tours.
The next step will be to allow the user to edit the tour in case they made a typo or if they just want to change part of its data.
Before we can do that, we need a way to identify the tour that we want to edit. 
So whenever we create a tour and add it to the `$toursData` array, we should also add an `id` property to give it a unique identifier (ID).

A unique ID could be a number that hasn't been used before.
We suggest you count the number of tours we have in `$toursData` and add one to it.
If we use the resulting number as an ID, the first tour would have ID 1, the second 2, and so on.
As long as we don't delete elements from the array, this ID will be unique.
Let's modify `create-tour.php` so it will set an ID for every tour:
