为通过Web表单发送的邮件添加cc

Question

我有以下代码将Web表单发送到Joomla的默认联系电子邮件。我需要将其发送到多个电子邮件地址，例如我们通过cc发送的电子邮件。

                session_start();

                $func->impromptu();
                $data = new Data();

                $from = $data->get_value("default_contact_from");
                $from_name = 'webmaster';
                $subject = 'Website Contact Submission';

                $notification_to = $data->get_value("default_contact_email");
                if(strpos($notification_to, ",")){
                    $notification_to = explode(",", $notification_to);
                }

                $ignore = array('view', 'option', 'contact_submit');
                $required = array('contact_name', 'contact_email', 'contact_phone');

                $mainframe =& JFactory::getApplication('site');
                $mainframe->initialise();


                $captcha_url = $conf->public.'captcha';

                if($_POST['contact_submit'] == 'Submit'){
                    //captcha check
                    if (!$_SESSION['securimage_code_value'] || $_SESSION['securimage_code_value'] != strtolower($_POST['captcha'])) {
                        $error[] = "Invalid captcha code entered";
                    } 
                    foreach($required as $v){
                        if(!$_POST[$v]){
                            $error[] = 'Missing required field: '.$v;
                        }
                    }
                    foreach($_POST as $k=>$v){
                        if(!in_array($k, $ignore)){
                            $body.= $k." : ".$v."\n";
                        }
                    }
                    if(!is_array($error)){
                        //post
                        $send = true;
                        if(is_array($notification_to)){
                            foreach($notification_to as $v){
                                $func->email($from, $from_name, trim($v), $subject, $body);
                            }
                        }else {
                            $func->email($from, $from_name, trim($notification_to), $subject, $body);
                        }
                        $func->system_message('Thanks for your submission!');
                        //$func->reload('Thanks for your submission!');
                    } else {
                        $func->system_message($error[0]);
                        //$func->reload($error[0]);
                    }

                }

                $tpl->assign('captcha_url', $captcha_url);

                $tpl->set_template('captcha', 'captcha.tpl.php');
                $func->css('contact.css');
                $func->js('jquery.js');
