ZF: view variable definition for layout

I have some controller Index. There I defined variable:

class IndexController extends Zend_Controller_Action
{
      function IndexController()
      {
           $this->view->some_val = 100;
      }
}

And the layout is like this:

<html>
<p><?= $this->some_val; ?></p>
<?= $this->getLayout()->content; ?>
</html>

But in th this case I get NULL instead of 100. I tried to define it in preDispatch function but result is the same. Could anybody help pls? Thanks to all in advance

One one would be as @Yanick Rochon wrote. Another way would be to assing variables directly to your layout(), e.g.

class IndexController extends Zend_Controller_Action
{
      function IndexController()
      {
           $this->view->layout()->some_val = 100;
      }
}

Then in your layout;

<p><?= $this->layout()->some_val; ?></p>

If you need to save a reusable variable, use the placeholder view helper 

public function indexAction() {
    $this->view->placeholder('some_value')->set(100);
}

and in any view script, or layout

echo $this->placeholder('some_value')->getValue();   // -> 100
