Помогите Пример кода как использовать RCON

Хотел бы посмотреть пример кода как можно выполнять RCON команду на другом сервере, гугли не нашёл

 

Как же это было сложно, держи. (c) разраб пхпмк

По RCON у меня подключается, а вот команду say Hello World не отправляет.[DOUBLEPOST=1493989538,1493960435][/DOUBLEPOST]Погуглил и всё таки нашёл api для RCON: https://github.com/Kronos666/rkon-core
Но всё равно спасибо. Тема закрыта
