Chat QQ with php

I recently used php to chat with QQ. you can search for QQ's http protocol on the internet. the implementation is very simple. I just tried it a little and wrote the following code, if anyone is interested, continue the study. If you have SDKs for j2_9 or major mobile phone manufacturers, it is good to study javaQQ. I want to take the test recently. I can only post it first. I want to explain it first. not all of them have been completed.
Code:

Feof ($ socket) {$ ret. = fgets ($ socket, 4096);} fclose ($ socket); $ this-> setRetValues ($ ret);} public function clearParams () {$ this-> postValues = ''; return true;} public function addParams ($ var, $ value) {$ this-> postValues. = urlencode ($ var ).
