I have some code that I wrote some code for an irc bot, part from a tutorial, and it will not sign into the server. Any help would greatly be appreciated.

<?php

//So the bot doesnt stop.

set_time_limit(0);

ini_set('display_errors', 'on');

    //Example connection stuff.

    $config = array( 
        'server' => 'irc.rizon.net', 
        'port' => 6667, 
        'nick' => 'Mlia', 
        'name' => 'Ihavenoname', 
        'pass' => 'meh', 
    );

class IRCBot {

    //This is going to hold our TCP/IP connection

    var $socket;

    //This is going to hold all of the messages both server and client

    var $ex = array();

    /*

     Construct item, opens the server connection, logs the bot in

     @param array

    */

    function __construct($config)

    {

        $this->socket = fsockopen($config['server'], $config['port']);

        $this->login($config);

        $this->main();

        $this->send_data('JOIN', '#tc');

    }

    /*

     Logs the bot in on the server

     @param array

    */

    function login($config)

    {

        $this->send_data('USER', $config['nick'].$config['nick'].' :'.$config['name']);

        $this->send_data('NICK', $config['nick']);

    }

    /*

     This is the workhorse function, grabs the data from the server and displays on the browser

    */

    function main()

    {

        $data = fgets($this->socket, 128);

        echo nl2br($data);

        flush();

        $this->ex = explode(' ', $data);

        if($this->ex[0] == 'PING')

        {

            $this->send_data('PONG', $this->ex[1]); //Plays ping-pong with the server to stay connected.

        }

        $command = str_replace(array(chr(10), chr(13)), '', $this->ex[3]);

        switch($command) //List of commands the bot responds to from a user.

        {

            case ':!mlia':

                $this->mlia($this->ex[4]);

                break;
        }

        $this->main();

    }

    function send_data($cmd, $msg = null) //displays stuff to the broswer and sends data to the server.

    {

        if($msg == null)

        {

            fputs($this->socket, $cmd."\r\n");

            echo '<strong>'.$cmd.'</strong><br />';

        } else {

            fputs($this->socket, $cmd.' '.$msg."\r\n");

            echo '<strong>'.$cmd.' '.$msg.'</strong><br />';

        }

    }

function Mlia($channel){
    $mlianumber = rand(0,436672);
    $mliapage = file_get_contents("http://mylifeisaverage.com/s/$mlianumber");
    $pattern = "<div class=\"sc\">(.|[\r\n])*?<\/div>";
preg_match("/$pattern/i",$mliapage,$match);
$match = $match[0];
$match = str_replace ("<div class=\"sc\">","",$match);
$match = str_replace ("</div>","",$match);
$match = str_replace ("\n","",$match);
$match = str_replace ("\r","",$match);
$match = trim($match);
$string = "4MLIA:1 $match";
send("PRIVMSG",$channel,$string);
}

    $bot = new IRCBot($config);
