Please help me print this array to my email- zend_mail

I'm so dang close. I'm trying to print the contents of a form to an email. Here's what I have. I'm able to pront the contents as an array to my view, but not send the values to the email.

public function indexAction()
    {
        $formData = array();
        $emailData = array();

    $form = new Application_Form_Contact();

        if ($this->_request->isPost()) {
            $formData = $this->_request->getPost();
            if ($form->isValid($formData)) {

                foreach ($formData as $d){
                    $emailData[] = $d;
                }

                 $mail = new Zend_Mail();

                 $mail->setFrom('me@me.com', 'user');
                 $mail->AddT开发者_Python百科o('me@me.com', 'joel');
                 $mail->setSubject('from form');
                 $mail->setBodyText($emailData);
                 $mail->send();

            } else {
                // bad stuff happens
            }
        }
        $this->view->form = $form;
    }
}

emailData needs to be a string.

$emailData = "Email content: ";
foreach ($formData as $d){
   $emailData .= $d . "\r\n";
}

Not the most elegant thing but it will work.
