I am the author of the PHP Debug and IntelliSense extensions, awesome to see this get publicity on HN (aside from the Devsense fiasco https://news.ycombinator.com/item?id=18538432, lol)! If you're passionate about PHP in VS Code and are missing some feature or see some bug, please don't be afraid to jump into the code and do a PR! I've built them as a community project from the start, with as many comments as possible and (the language server) intentionally written in PHP so PHP devs can contribute. I actually don't get to write any PHP anymore nowadays, but I am always happy to review PRs!
