Been there, done that (i.e. already thought about these).

Been here too - that's why my original question looks the way it does. So, the
answer is actually "No, there's no smarter way than looping in the PHP" - am I
correct?

I especially liked the bit above. Never used file() myself so the code looked
quite awkward at first glance...

Another feature of PHP I always overlooked! I'm learning of a lot of overlooked
features from your e-mail!

You could also do a set_time_limit(30) INSIDE the loop. This resets the timeout
counter, so it's a better option.

...which further speeds down the overall process, plus induces a lot of delays
which have to be dealt with (quite complicated, I must say). I think simply
reloading from time to time and sending the last 10 lines for example might be a
better solution.

Yes, they did - you opened my eyes to a couple of useful but neglected features
of PHP.
Thanks for taking the time to answer!
