I have written an in-depth blog "Zend\Form\Element\Select and Database-Values" about this topic. Basically though, this is what you have to do:

Basically all you have to do is Query the Database inside your Form for the Data. For this you need the DB-Adapter to be available inside your Form, which is done by Dependency-Injection. Since the DB-Adapter is required for your Form to function correctly, i'd suggest Setter-Injection.

Inside your getServiceConfig() do this:

return array('factories' => array(
    'namespace-form-formname' => function($sm) {
        $dbA  = $sm->get('Zend\Db\Adapter\Adapter');
        $form = new \Namespace\Form\Formname($dbA);

        return $form;
    }
));

This will inject the Zend\Db\Adapter\Adapter into your form, which should already be valid though other configuration. Then you need to modify your form code a little bit:

public function __construct(\Zend\Db\Adapter\Adapter $dbA) {
    parent::__construct('form-name');

    // Do the DB-Query here. You got the DB-Adapter
    // http://zf2.readthedocs.org/en/latest/modules/zend.db.adapter.html
    $selectArray =  array(
        'key' => 'value',
        'key' => 'value',
        'key' => 'value',
    ); // obviously, this is just a fake-$selectArray demonstrating 
       // what the output of your Queries should be

    // Add your Form Elements here
    // use $selectArray as value_options of your desired select element
}

And that's basically it. Sadly i can't give you an concrete example, as i've never worked with Zend\Db, but i assume this will get you started.

PS: In your controller, call the form like this:

$form = $this->getServiceLocator()->get('namespace-form-formname');

Try:
// add code on controller
$arrPortalId = array();
$results = array('1' => 'portal 1', '2' => 'portal 2', '3' => 'portal 3',); // this part change your database value
foreach ($results as $key => $val) {
$arrPortalId[$key] = $va;

$dataParams['portalId'] = $arrPortalId;
$form = new UserForm($dataParams);
