Both are different languages, and both work in different ways.
The interesting part to me is how the difference to serve the set same features is written.
One is an older language and the other is a older-modern language.
It's the same with mechanics. I would be more interested in watching and learning how an 1949 carousel with a vinyl player in the centre works than a 2024 carousel with an iPhone in the centre.
First of all, the implementation will likely be the same from a technical perspective and differ mainly in that the C code will have more boiler plate. Secondly, did you actually read the source code of this project? I feel like reading a PHP one would be more enjoyable purely because it would be more terse.
