So if you attended the final keynote at WCEU you would have seen the WP Playground demo video.
I’ve been following WP Playground for some time now, and I was able to meet with the developer behind the project, Adam Zieliński, who showed me the interactive code block, which I had to try out.
Below is the simplest implementation of the block:
What I love about it is that it works like this whether you’re writing in the editor or displaying the code on the front end. So I can test this code and see what it will do before I publish this post.
As far as I can see, it supports anything that PHP supports, even working with classes, and setting types for function or method parameters.
How I wish I had this functionality when I first started blogging about learning PHP!
