cURL only gets Empty Replies from Server. Wrong configs?

[Fortbruhnite]

First, I wanted to say, that I really like your (codler) work and it is impressive, that you managed to write a whole Bitcoin Miner in PhP.

So, my issue is, that since the old pool (http://pit.deepbit.net/) is dead it cant be mined on anymore. I tried to use a new pool (btc.f2pool.com:3333) but I cant seem to get the miner to work.
My Configs are:
$host = 'btc.f2pool.com';
$port = 3333;
$user = 'fortbruh1';
$pass = 'password here';

The Pool I tried to mine from suggests, that you should use "stratum+tcp://btc.f2pool.com:3333" as the Pool URL. This wont work since stratum+tcp:// cant be at the front and the Port 3333 already has its own Variable in the PhP Code.
I tried a lot of combinations, but cant seem get rid of the "Fatal error: Uncaught Exception: curl:CURL error : Empty reply from server in" Exception.

Maybe it wont work at all because the Bitcoin-phpMiner is too outdated, but I hope there is someone who understands the configurations for this Miner better than I do and can help me out.

Thanks! :)
