For a programming language mostly out of favor, the effort to get a framework right and find the right audience to use this over existing options will be tricky. Good luck!
In true JavaScript fashion, I decided to learn PHP again by building a framework to put all the pieces together in my brain.
I absolutely love Hono.dev, and decided to base the PHP framework on that. Dumbo isn't intended to compete with Laravel, Symphony or Slim, if anything, it's something people can use in production, but also contribute to and be used as a learning resource for others.
