PHP's model is different, not a mistake.

It has proved successful so far. The shared-nothing, short-lived process avoids classes of issues such as with slow memory leaks, accidentally blocking event loops, and shared memory threading issues.

Most PHP sites will utilise php-fpm, so it isn't really true that each request will spawn another PHP process.

The language historically hasn't been that great, but its shared-nothing architecture has always been the good part.
