fputs只返回未知命令

I have a very small script inwhich I'm trying to get it to post a command in IRC.

<?php

    set_time_limit(0);
    $socket = fsockopen("irc.twitch.tv", 6667);
    fputs($socket,"USER greatbritishbgbot
");
    fputs($socket,"PASS oauth:95uf89rv74gawp93ilfafeqnihpxb74
");
    fputs($socket,"NICK greatbritishbgbot
");
    fputs($socket,"JOIN #greatbritishbg
");
    $ircChannel = "#greatbritishbg";

    while($data = fgets($socket, 128)) {
        $msg = "test";
        fwrite($socket, "PRIVMSG " . $ircChannel . " :" . $msg . "
");
        echo nl2br($data);
        flush();
    }


?>

Every time I execute this, I receive the error: greatbritishbgbot HELP:Unknown command. What is the correct way of using fputs to run an IRC command?

Edit: This question was requested to be closed and downvoted because I am apparently asking for debugging information. Which is incorrect. I have asked for an explanation into how one should use fputs in comparison to how I use it.

I ended up using WildPHP which only needed me to modify a config file.

I highly recommend it.
