class EmployeeController extends Zend_Controller_Action
{
    public function init()
    {

    }
    public function indexAction()
    {

      $form = new Default_Form_Empdetails();
       $this->view->form = $form;
        $request = $this->getRequest();
          $formData = $request->getPost();
        if ($request->isPost()) {
            if ($form->isValid($request->getPost())) {  
                $empName = $form->getValue('empName');
                $empAddress = $form->getValue('empAddress');
                $emp = new Default_Model_DBTable_Employee();
                $emp->addAlbum($empName, $empAddress);
              $this->_helper->redirector('index');
            } else {
                $form->populate($formData);
            }
        }

    }
}
?>

Kindly help me

It may be because of extra white spaces after php closing tag (?>) in some file.

Also read this Post:

PHP development: why redirects don't work (headers already sent)

• Any HTML output, including the DOCTYPE declaration or any HTML tag, including the head of the page
• Extra whitespace before the opening PHP tag of the page, or outside the PHP tags of an include file
• Using print() or echo before calling header() or session_start()
• Using virtual() to include files
• Using the byte-order mark (BOM) at the beginning of a page

For example:
