I agree that it should not matter but there are people out there who really have strong feelings about PHP. I understand those strong feelings because PHP was very popular since it was on every shared host and it was super easy to quickly whip up scripts that render dynamic pages back in the day. That ease had consequences that PHP is trying to dig out from under to this day. I personally reach for PHP first for all my personal web projects. It's where I am most comfortable. I write C++, Rust, Python, C#, and JS in various capacities both personally and professionally and I always go to the first language I learned whenever I want to prototype, PHP. That said, I agree with the sentiment you are expressing. If the app works, and people enjoy using it, the underlying language only matters to other devs who might work on it and that is it.
