我通过api以json的形式获取一些数据：
响应标题：

答复数据：

{
    "code": 200,
    "result": {
        "id": 3075531,
        "stock_id": 184445,
        "stock_article": "Parfum 2 ml 047 women",
        "selections": [

                "label": "11",
                "price": 1,
                "pricelist": null,
                "pricelist_type": null,

        ],

    }
}

然后解码和做 foreach() 要仅输出我需要的变量，请执行以下操作：
代码

$decodedJson = json_decode($html, true);
foreach($decodedJson as $answer) {
    echo 'Item:' .$answer['name'].' available '.$answer['amount'].'pcs.'; 
}

但我被卡住了，因为在输出中得到了重复项（echo行没有变量，而echo行有变量，无法解决这个问题，有人能帮忙吗？
输出

Item: available pcs.Item:Parfum 2 ml 047 women available 10pcs.
