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.

## Why submit data through the request body?

Submitting form data using query parameters is nice and easy, but it should only be used for really simple forms that only have short-term effects.
Most forms are used to collect information from the user, which is then going to be saved to a database.
Some forms have sensitive or personal data that should not visibly end up in the URL.
Imagine a username and a password being submitted as query parameters: `/register username=coolguy1984&password=ilovecookies`.
This URL ends up in the browser's history.
The username and password will also show up in server log files.
So in practice, most form data will be submitted not as query parameters but, as part of the *request body*.
