    {
    switch( $badword['type'] )
    {
    case 'word' :
    $badword['badword'] = str_replace( '\*', '[\w~@\#$%^&*()_+|]*', preg_quote($badword['badword']) );
    //$this->search_array[] = '#(^'.$badword.'(?=\s|$))|((?<=\s)'.$badword.'(?=\s|[.;:,?!]|$))#i';
    $this->search_array[] = '#(\b'.$badword['badword'].'\b)#i';
    break;
    case 'string' :
    $badword['badword'] = str_replace( '\*', '[\w~@\#$%^&*()_+|]*', preg_quote($badword['badword']) );
    $this->search_array[] = '#('.$badword['badword'].')#i';
    break;
    case 'regexp' :
    $this->search_array[] = '#('.$badword['badword'].')#i';
    break;
    }
    }

    I did not go over everything carefully, in part because it's difficult to read code snippets if you do not wrap them in the forum's [php]...[/php] bbcode tags. One thing I noticed though is that if you are going to use preg_quote(), you should use the optional 2nd parameter to specify the regexp delimiter you plan on using (in this case apparently the "#").
