In a different life I had to maintain a website based on the Drupal CMS and also one based on the then-popular Laravel PHP framework, and in both environments testing was common and well-supported. As much as I dislike PHP, such a blanket statement does not hold up.
If you have to build the kind of site that needs to do the things that WordPress does, it's a great choice.
PHP, unfortunately, is never going to get away from the reputation that it earned and some of the choices it's stuck with, but it's a perfectly adequate language to develop web software with and the tooling these days is pretty good.
It's not my choice to use, but I'm happy to use it in a modern context.
In your experience, what are better web server languages and frameworks?
