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

# Allowing an administrator to upload a picture
A picture of the destination is missing in the catalog of tours.
We would like to allow administrators to upload a picture and show that picture on the detail page of the tour (which, by the way, we don't have yet).
Allowing users to upload files to the server is even more of a potential security risk than any other thing we did before.
People could upload all kinds of bad files, files that look like pictures but are actually programs, pictures that show inappropriate things, or pictures that crash the browser, etc.
However, since only an administrator should be able to upload pictures, we don't have to assume the worst.

We need several ingredients that we will add one by one:

1. The create and edit form should be prepared for uploading a file.
2. After the form has been validated, we should take the uploaded file and move it to a place inside the document root.
3. We should save the filename in `tours.json` as well.
4. We should then show the image on the details page of a tour.

Learn how to allow the administrator to upload a picture of the destination and then create a details page for the tour.
