Php 通过web服务检索数据

我使用外部PrestashopWeb服务检索产品 示例如何恢复此标题、数量等

$productResources = $webService->get(array('resource' => 'products','active' => '0', 'id' => (int)$product_id));
$productWB = $productResources->product;
echo $productWB->name->language; 

result = "{"@attributes":{"id":"2"},"0":"Pantalon de costume - Bleu-Ile de Paques"}"

这项工作：

$productResources = $webService->get(array('resource' => 'products','active' => '0', 'id' => (int)$product_id));
$productWB = $productResources->product;
$productb = get_object_vars(json_decode($productWB->name->language));

echo $productb[0];

如何展示“Pantalon de coust-Bleu Ile de Paques”
