循环通过 IBM Watson Assistant Webhook 结果

Question

我的 webhook 返回这个结果集（虚拟数据）：

{
    "searchResults": [
        {
            "fullName": "William Patterson",
            "title": "Web Developer",
            "phoneNumber": "133-959-0421",
            "officeNumber": "31",
            "board": "BRD",
            "unit": "TRB",
            "manager": "Martinez, Laura M."
        },
        {
            "fullName": "Justina Patterson",
            "title": "Web Developer",
            "phoneNumber": "133-959-0421",
            "officeNumber": "31",
            "board": "BRD",
            "unit": "TRB",
            "manager": "Martinez, Laura M."
        }
    ]
}

我能够通过索引号成功获取结果，如下所示：

<? $webhook_result_1.searchResults[0].fullName ?>

但是，遍历该结果集并显示多个结果的语法是什么？ 我在任何地方都找不到文档。
