我有一个 php 脚本来加入这个 IRC 服务器上的频道：irc.worldnet.net 感谢服务器的响应，我可以说我成功加入了频道，并且机器人在用户列表中。但是，此命令：

MSG bot_nickname hello my friend !

发出“味精：未知命令”响应。当我发送此行时：

PRIVMSG bot_nickname : hello my friend !

机器人没有响应（无论如何我没有任何错误消息）。我发送的命令有问题吗？

这是我使用的 php 代码：

<?php

$channel_sent = false;
$channel_joined = false;
$msg_sent = false;
set_time_limit(0);
ini_set('display_errors', 'on');

$config = array(
    'server' => 'irc.worldnet.net',
    'port' => 6667,
    'nick' => 'cesame'.rand(),
    'channel' => '#nc-irc-challs'
);

$server = array();
$server['SOCKET'] = @fsockopen($config['server'], $config['port'], $errno, $errstr, 2); 

if($server['SOCKET'])
{
    SendCommand("PASS NOPASS\n\r");
    SendCommand("NICK " . $config['nick'] . "\n\r"); 
    SendCommand("USER " . $config['nick'] . " USING PHP IRC\n\r");    
    SendCommand("JOIN " . $config['channel'] . "\n\r");

    while(!feof($server['SOCKET'])) {
            ReadServer();
            flush();
            sleep(1);
    }
}

function ReadServer(){
    global $server;
    global $config;
    global $channel_joined;
    global $channel_sent;
    global $msg_sent;
    $server['READ_BUFFER'] = fgets($server['SOCKET'], 1024);
    echo "[RECEIVE] ".$server['READ_BUFFER']."<br>\n\r";  

    if(substr($server['READ_BUFFER'], 0, 6) == "PING :") { 
        SendCommand("PONG :".substr($server['READ_BUFFER'], 6)."\n\r"); 
    }
    if(strpos($server['READ_BUFFER'], "#nc-irc-challs :End of /NAMES list")){
        $channel_joined = true;
    }
    if(trim($server['READ_BUFFER']) == "" && $channel_joined &&!$msg_sent) {
        SendCommand('PRIVMSG Daneel : .challenge_caesar start' . "\n\r");
        $msg_sent = true;
    }
}

function SendCommand ($cmd)
{
    global $server; //Extends our $server array to this function
    @fwrite($server['SOCKET'], $cmd, strlen($cmd)); //sends the command to the server
    echo "[SEND] $cmd <br>"; //displays it on the screen
} 

?>

所以我听从了你的建议。这是我得到的日志：

The IRC server generally does not send empty strings.

If you want a command to be issued once the BOT is in the channel, you should be sending it as soon as you know it's in the channel, which is at the end of the /NAMES list, or once you receive the TOPIC.

Also, the syntax for PRIVMSG is as follows:

PRIVMSG <NICKNAME> :<MESSAGE>

Without the space after the :. If the recieving end is set to respond to .command but gets  .command, that may be the problem.
