How to pass array values ​​in a query string ...

<?php 
                foreach ( $Cart->getItems() as $order_code=>$quantity ) :
                $pname[]= $Cart->getItemName($order_code);
                $item[]= $Cart->getItemPrice($order_code);
                $qty[]=$quantity;
                endforeach;
                ?>
                <form action='expresscheckout.php?amt=<?php echo $total_price; ?>&item_name=<?php echo $pname; ?>&unit=<?php echo $item; ?>&quan=<?php echo $qty; ?>' METHOD='POST'>
<input type='image' name='submit' src='https://www.paypal.com/en_US/i/btn/btn_xpressCheckout.gif' border='0' align='top' alt='Check out with PayPal'/>
</form>

This is my sample code., For the above code example, do I need to pass a query string at my action url, which is expresscheckout.php expression? amt = 100. etc., fall under $ pname [], $ clause [], $ pcs [].

Waiting for output in expresscheckout.php

<input type="checkbox" id="colors[]" value="blue" /> Blue
<input type="checkbox" id="colors[]" value="green" /> Green
