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

# Need for authentication

A web application usually has:
1. A public part
2. A part for known users who are logged in
3. A part that is only accessible to administrators

Public pages will be accessible by so-called *anonymous* users. For other pages, like a list of previously created orders or a page where the user can edit their profile, these users will need to authenticate first.
Authentication refers to establishing the identity of the user.
After they provide their username and password, we verify that it is in fact them and not someone else.
After all, nobody else is supposed to know someone else's password.
