MercadoPago PHP SDK quantity error

I'm using the PHP MercadoPago SDK module. Here is my code:

$mp = new MP("CLIENT_ID", "CLIENT_SCRET");  

foreach ($_SESSION["carrito"] as $value){
    $itemCode  = $value['tagme']; 
    $itemDesc  = get_pedido($itemCode);        
    $itemQty   = $value['cant'];  // it comes from $_POST['cant']       
    $unitPrice = $value['unit_price'];

    $items[] = array(
        "title" => $itemDesc,       
        "quantity" => $itemQty,
        "currency_id" => "ARS",
        "unit_price" => $unitPrice
    ); 
}

$preference = array(
    "items" => $items,
    "payer" => array(
        'name'  => $name,
        'email' => $email
    ),
    "back_urls" => array(
        'success' => 'http://example.com/success.php',
        'pending' => 'http://example.com/pending.php'
    )
);
echo '<pre>';print_r($items); echo '</pre>';
$mp->sandbox_mode(TRUE);
$preferenceResult = $mp->create_preference($preference);

The $items outputs as below:

Array
(
    [0] => Array
        (
            [title] => Test Product
            [quantity] => 1
            [currency_id] => ARS
            [unit_price] => 36
        )

    [1] => Array
        (
            [title] => Shipping Cost
            [quantity] => 1
            [currency_id] => ARS
            [unit_price] => 42
        )

)

But I got the following error:

Fatal error: Uncaught exception 'Exception' with message 'quantity must be a number' in /home/..../public_html/mercadopago-sdk/mercadopago.php:227 Stack trace: #0 /home/..../public_html/mercadopago-sdk/mercadopago.php(240): MPRestClient::exec('POST', '/checkout/prefe...', Array, 'application/jso...') #1 /home/..../public_html/mercadopago-sdk/mercadopago.php(126): MPRestClient::post('/checkout/prefe...', Array) #2 /home/..../public_html/confirm.php(140): MP->create_preference(Array) #3 {main} thrown in /home/..../public_html/mercadopago-sdk/mercadopago.php on line 227

Any idea?

I solved the problem by typecasting the quantity to INT.

foreach ($_SESSION["carrito"] as $value){
    $itemCode  = $value['tagme']; 
    $itemDesc  = get_pedido($itemCode);        
    $itemQty   = $value['cant'];  // it comes from $_POST['cant']       
    $unitPrice = $value['unit_price'];

    $items[] = array(
        "title" => $itemDesc,       
        "quantity" => intval($itemQty), // this solved the error        
        "currency_id" => "ARS",
        "unit_price" => $unitPrice
    ); 
}

My quantity seems to be string which comes from hidden and stores in session:

<input type="hidden" name="cant" value="1" />

But, MercadoPago API expects an integer in that field. So, I had to use intval().
