We covered a lot in this PHP tutorial: from PHP variables and syntax to PHP arrays, loops, functions, and scope. You also learned how to retrieve and handle user input from PHP GET and POST requests, as well as how to use the session to persist data between different pages. Not only that, but we implemented a real web app using these simple PHP skills!
Thank you so much for following along. Please feel free to contact me via Twitter or the Envato Tuts+ forums if you have any questions!
