Ready to Grow Your PHP and Go Web Development Skills?
Hi 👋🏻. I'm Matt. You might know me better as settermjd on Twitter. For over 10 years, I've been teaching developers how to build web-based applications with PHP, through tutorials, my books and courses, and content I've written for other sites. More recently, I've been showing how to do so with Go too!
As modern web-based applications require a broad range of knowledge and skills, it can be hard to know what to learn and in what order. To make matters worse, no matter if you're a freelancer or a full-time employee, there's always another ticket to complete or a release to push out.
Given that, finding time to improve your skills can be hard to come by. So, you need a guide you can rely on. I'd love to be that for you.
Why? Besides loving writing and teaching web-based development, each tutorial is:
- Written in plain English by me; not AI!
- Tested for accuracy
- Shows the minimum required version of PHP or Go, and the library and package versions required
- Contains links to further information
- Plus so much more!
If this sounds like what you're after, head to the blog to get started. If you're short on time, start with the latest tutorials below.
