@BarryCarlyon But the problem I am having is my .txt file always added data which is not related to chat something like below.
:tmi.twitch.tv 001 mittultwitch :Welcome, GLHF!
:tmi.twitch.tv 002 mittultwitch :Your host is tmi.twitch.tv
:tmi.twitch.tv 003 mittultwitch :This server is rather new
Hence my full .txt file is not in json format. I do not want to add above content in a file but its always added may be due to below code.
fwrite($socket,"PASS ".$pass."\r\n");
fwrite($socket,"NICK ".$nick."\r\n");
fwrite($socket,"JOIN ".$chan."\r\n");
So I am confused how can I not add above content as well. As I only want to get chat response in my json file.
