This course is for people who have already learned the basics of PHP (or just finished the "Learn PHP from Scratch" course) and want the bigger picture of making big web applications with this language.

First, you'll learn how all PHP web applications communicate with the world and how to turn multiple source code files into one application. Then you'll learn multiple approaches to structuring the whole application. It will help you write code that's easy to maintain. Also, this is a common topic for job interview questions.

Next, you'll learn different data storage methods, from user sessions to databases. This course doesn't duplicate the official documentation but instead provides an overview of the various tools you can use. You'll learn how to use them in PHP, their tradeoffs, and how to pick what's best for your project.

Finally, you'll learn how to make automated tests for your project to ensure that it works as expected.
