Please try following method. Maybe it will useful to you.

Use multi select element like below:

$multi = new Zend_Form_Element_Multiselect('users');
$multi->setMultiOptions(array(
    //'option value' => 'option label'
    '21' => 'Milap',
    '22' => 'jay',
    '23' => 'Sandip'
));
$form->addElement($multi);

You can get the values of element like this:

public function indexAction()
{
    $form = new MyForm();

    $request = $this->getRequest();
    if ($request->isPost()) {

        if ($form->isValid($request->getPost())) {

            $values = $form->getValues();
            $users = $values['users'];
            var_dump($users);
        }
    }
    $this->view->form = $form;
}

Here , $users will contain an array of the values that have been selected:

array(
    0 => '21',
    1 => '23'
)

Good luck.
