The PHP language keeps aging like a fine bottle of wine. With every new release, the language that runs the web keeps getting faster & stronger. Community support is increasing, and platforms such as Laravel & Magento offer enterprise features. There has never been a better time to learn PHP.

In this course, you will learn all about PHP 8's syntax & new features. You'll also learn how to create variables, functions & classes. You may even pick up tidbits & tricks that I've learned along the way as my over 20 years as a PHP programmer.
