PHP_EOL depends on your host system, it’s \r\n
on Windows.
I don’t really want to use what Lerdorf intended, PHP <= 4 was horrible, 5.x was mainly getting slowly rid of nonsense and with 7.x PHP started its slow path of redemption and entered its modern era.
While Lerdorf’s vision was great at that time for its intended use case, I wouldn’t want to build anything serious in it.
That game’s really great, definitely better than at launch. Still many bugs, but it’s been fun playing with my partner on our local server.
