How get access to input form dynamic create form in Zend

Question

I tried build form for a list of books. And i want make to update every quantity position in every row. I thought i can create dynamic form with one field like quantity.

$zendFormUpdate = new Zend_Form;
for ($i = 0; $i < 4; $i++){
    $quantity[$i] = $this->addElement('text','quantity'.$i,[
        'required' => false,
     ]);
}
$this->view->forms = ['formupdate' => $zendFormUpdate];

And now i would like ask you, how can i get this fields ? I am using code below but i can't get anything

<html>
    <body>
        <p>
        <form>
            <?php for ($i = 0; $i < 4; $i++){ ?>
            <?php echo $this->forms['formupdate']->quantity.$i; ?>
            <?php } ?>
        </form>
        </p>
    </body>
</html>

Try:

// note the s after ->form, as well
$this->forms['formupdate']->getElement( 'quantity' . $i );

But since it's a typographical error, this:

$this->forms['formupdate']->{ 'quantity' . $i };

should work as well. I forgot you could access Zend_Form elements in this manner too.

Yes $this->forms['formupdate']->getElement( 'quantity'.$i ) works perfect for me THANK YOU

@user4347073 You're welcome! I missed the $i at first. I've added those, so now you can see how to use the $i in the alternative syntax, as well.
