Removing a comma

[smokey]

Trying to get the hang of the plugin system. I'm trying to remove the comma that separates the moderators on the moderator column. Eg it outputs mod1, mod2, mod3; basically i want to remove the comma and space for something I'm trying to accomplish. The thing is I do not want to do a file edit.

Here is the code from the function_forumlist.php

PHP Code:

                $showmods = array();
                $listexploded = explode(',', $forum['parentlist']);
                foreach ($listexploded AS $parentforumid)
                {
                    if (!isset($imodcache["$parentforumid"]) OR $parentforumid == -1)
                    {
                        continue;
                    }
                    foreach($imodcache["$parentforumid"] AS $moderator)
                    {
                        if (isset($showmods["$moderator[userid]"]))
                        {
                            continue;
                        }

                        ($hook = vBulletinHook::fetch_hook('forumbit_moderator')) ? eval($hook) : false;

                        $showmods["$moderator[userid]"] = true;
                        if (!isset($forum['moderators']))
                        {
                            eval('$forum[\'moderators\'] = "' . fetch_template('forumhome_moderator') . '";');
                        }
                        else
                        {
                            eval('$forum[\'moderators\'] .= ", ' . fetch_template('forumhome_moderator') . '";');
                        }
                    }
                } 


I want to insert a hook (forumbit_moderator) that will stop the execution of the code

PHP Code:

                        $showmods["$moderator[userid]"] = true;
                        if (!isset($forum['moderators']))
                        {
                            eval('$forum[\'moderators\'] = "' . fetch_template('forumhome_moderator') . '";');
                        }
                        else
                        {
                            eval('$forum[\'moderators\'] .= ", ' . fetch_template('forumhome_moderator') . '";');
                        } 


And replace with

PHP Code:

                        $showmods["$moderator[userid]"] = true;
                        eval('$forum[\'moderators\'] = "' . fetch_template('forumhome_moderator') . '";'); 


Tried many things and just cannot get it to work right. Any suggestions?

Thanks!
