Parsing Help (BBCode) - New Topic

Well, it seems that I somehow killed the last page. So, I'm starting this one. I've been to the tutorial on the site, and it doesn't work (in fact, it outputs SMF-breaking text). Any ideas?

parse code:

 

<?php

    var $parse_bbcodes; // Boolean - true = on | false = off
    var $parse_smilies; // Boolean - true = on | false = off
    var $smiley_url;    // String  - sets the URL to the smiley folder
    
    function parser()
    {
        // Set some default values:
        $this->parse_bbcodes = true;
        $this->parse_smilies = true;
        $this->smiley_url    = "/smileys";
    }

    {

        if($this->parse_bbcodes)
