But The information is being pulled from a pre-filled hence you need,
Something like

//$items=array(
if (isset($_POST["submit"])){

foreach ($_POST['quantity'] as $key => $value) {
  if( $value > 0){
      if(isset($_POST['with_gst'][$key])){
	    $unit_cost = 63.00;
	}else{
      $unit_cost = 60.00; //no gst included
  }
$newsubtotal = ($unit_cost * $value);
$quantity = ($value);
$itemssubarray[]= array(
'url' => "https://www.pdsolutions.ca/images/newwhiteheader.png",
'description' => $_POST['description'][$key],
'product_code' => $_POST['id'][$key],
'unit_cost' => $unit_cost,
'quantity' => $quantity,
);
	   
}  
$subtotal = $subtotal+ $newsubtotal;
$items_count++;
}
array_push($items, $itemssubarray);

}
//);
					      
  $cartarray[] = array(
  "cart"=>array( $items
  ),
 'subtotal' => $subtotal,
  "tax"=>array(
  'amount' => ($subtotal * 0.05),
  'description' => "GST",
'rate' => "5.00",
),
);
