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.

# Differences between editing and creating tours
Here are some differences between `edit-tour.php` and `create-tour.php`:

- In `edit-tour.php`, we have a tour ID provided as a query parameter. We put it inside a variable so we can use it later. When there is no `id` query parameter, it is technically a bad request, so we might show an error page, but for now, we just redirect the user to the list of tours.
- In the title of the page (the `<h1>` element), we indicate that the user is now editing the tour with the given ID.


# Functions required for editing tour data
The only missing ingredients are:

1. A function that can load the data of a single tour that we can use as the normalized data to feed into the form. That way, the form will show the current tour data, allowing the user to change it.
2. A function that can save the data of a single tour to `tours.json` when the user has submitted the form.

Finally, let's implement the functionality of editing tour data.
