PHP is extremely simple to use. That makes it extremely simple to onboard new people and also to support. Complexity brings associated costs, sometimes bigger than the development itself.
Last time I created a Laravel app it created dozens of default files and folders for me. How is that simpler than Go/Gin or Python/Fastapi? When does the extremely simple part come in?
You don't have to use Laravel. If you want more advanced stuff to be built in, go for it, but I can write reasonably complex apps with plain PHP. How simple is it? I showed a DBA with no programming experience (other than SQL) to make a change in an existing app in ~ 2 hours. The change was a new feature in the app, about ~ 100 loc. I also gave a complete non-technical colleague a small PHP application to own and support and it works quite fine 2 years later.
For one, PHP doesn't require bundlers to work, nor does it require compilers, transpilers, watchers or whatever. You just save your code in your editor of choice and that's it.
The proposition was PHP, Laravel, Inertia and React/Vue. Pretty sure Inertia is basically a transpiler to JS, and building the components in React will use a watcher for compilation. Not sure if it has TypeScript support.
Also, you still run artisan to view your code after you save. Same thing with Python's FastAPI: I run FastAPI's server. I just save my code just like PHP.
