问题


I have a php script to join a channel on this IRC server: irc.worldnet.net Thanks to the server response I can say that I joined the channel successfully, and that the bot is in the users list. However, this command:

MSG bot_nickname hello my friend !

issues an 'msg: unknown command' response. An when I send this line:

PRIVMSG bot_nickname : hello my friend !

There is no response from the bot (I don't have any error message anyway). Is there something wrong with the commands I send ?

Here is the php code that I use:

<?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
} 

?>

So I followed you advices. This is the logs that I Get:

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.
