php - List multiple items through Paypal Express checkout using Omnipay & Laravel 4 -

is possible list products in sites "cart" on paypal. ask because paypal says "descriptions" instead of description , nicer having combined total unhelpful description of "your basket"

$request = $gateway->purchase([             'amount' => '150.00',             'currency' => 'gbp',             'description' => 'your basket',             'returnurl' => 'http://localhost:8080/checkout/success',             'cancelurl' => 'http://localhost:8080/checkout/cancel'         ])->send(); 

the documentation vague or may have overlooked possibility i've tried:

 $request = $gateway->purchase([                 'amount' => array('100','200'),                 'currency' => 'gbp',                 'description' => array('prod1','prod2'),                 'returnurl' => 'http://localhost:8080/checkout/success',                 'cancelurl' => 'http://localhost:8080/checkout/cancel'             ])->send(); 

&
$request = $gateway->purchase([data],[data])->send();

where data follows above layout.

i found post on github explains how achievable.

setitems function added array of items can passed so:

$request = $gateway->purchase([             'amount'=>'70.00',             'returnurl' => 'http://localhost:8080/checkout/success',             'cancelurl' => 'http://localhost:8080/checkout/cancel'         ])->setitems(array(             array('name' => 'item1', 'quantity' => 2, 'price' => '10.00'),             array('name' => 'item2', 'quantity' => 1, 'price' => '50.00')         ))->send(); 

something note
request fail if purchase amount not equal sum of array of items.
