php - how make these variables dynamic in foreach loop -

i have cart data , want use paypal want make cart data formate

code:

$item_1 = new item(); $item_1->setname('item 1') // item name     ->setcurrency('usd')     ->setquantity(2)     ->setprice('15'); // unit price  $item_2 = new item(); $item_2->setname('item 2')     ->setcurrency('usd')     ->setquantity(4)     ->setprice('7');  $item_3 = new item(); $item_3->setname('item 3')     ->setcurrency('usd')     ->setquantity(1)     ->setprice('20');  // add item list $item_list = new itemlist(); $item_list->setitems(array($item_1, $item_2, $item_3)); 

you can define varying data in assoc array first:

$data = array(   array(     'quantity' => 1,     'price' => '15'), ... // etc ); 

then iterate on , add result array:

$result = array(); for($i = 0; $i < count($data); ++$i) {   $obj = new item();   $obj->setname('item ' . ($i+1)) // item name         ->setcurrency('usd')         ->setquantity($data[i]['quantity'])         ->setprice($data[i]['price']);    $result[] = $obj; } $item_list = new itemlist(); $item_list->setitems($result);
