PHP 7.4: What It Is, Why It Still Matters, and What Comes Next

When you hear PHP 7.4, a specific version of the PHP scripting language released in late 2019 that brought performance improvements and new syntax features. Also known as PHP 7.4.0, it was the last major update before PHP 8 arrived, and it still runs on thousands of live websites today. It wasn’t flashy, but it cleaned up old code, made things faster, and gave developers tools to write cleaner, safer apps. If you’re maintaining an older WordPress site, a legacy e-commerce store, or a custom business tool built around 2020, you’re probably looking at PHP 7.4 right now.

PHP 7.4 isn’t dead—it’s just no longer supported. That means no security patches, no bug fixes, and no official updates since November 2022. But here’s the thing: PHP 8.3, the current stable version of PHP that brings even better speed, type safety, and error handling didn’t erase PHP 7.4. It built on it. Features like typed properties, null coalescing assignment, and arrow functions from PHP 7.4 are now standard in PHP 8.3. So when you learn PHP today, you’re still using the same core ideas that made 7.4 useful. And if you’re fixing a site stuck on 7.4, you’re not just updating code—you’re upgrading security, performance, and reliability.

Many of the posts here talk about what’s real in web development today: WordPress, the content management system that runs nearly 40% of all websites and still relies heavily on PHP needs PHP to work. So does Etsy, Wikipedia, and a ton of small businesses that can’t afford a full rebuild. You don’t need to be on the latest PHP version to build something useful—but you do need to know why staying on old versions is risky. The posts below cover what PHP really looks like in 2025, how it compares to JavaScript and Python, and whether learning it still makes sense if you’re starting out. You’ll find real answers about upgrading, replacing, or simply understanding the code that keeps parts of the web running.
