php - Symfony2 - Get Form value, not key -

i'm new symfony2 (version 2.7) , i'm trying value submitted form. using $form->getdata(), index corresponding selected value in list.

for example, assuming $test array:

$form = $this->createformbuilder($test) ->add('abc', 'choice',     array('choices' => array(         '0' => 'option1',         '1' => 'option2',         '2' => 'option3'     ))) ->getform(); $form->handlerequest($request); if ($form->isvalid()) {     $data = ($form->getdata()); } 

then, $data 1 if select option2. i've tried set choices_as_values true, got array indexes in drop-down list.

what can $data equal option2 ?

$values = array('option1', 'option2', 'option3');  $form = $this->createformbuilder($test) ->add('abc', 'choice', array('choices' => $values)) ->getform();  $form->handlerequest($request);  if ($form->isvalid()) {     $data = $form['abc']->getdata();      //returns option1 if option1 selected etc..     $choice = $values[$data];      //returns choice value     $choice = $data; }
