JSON关联数组数组结构

Question

我不确定这是否会被视为json结构的正确格式。基本上我想要的是一组关联数组。我的json数据：

{
"notifications": [{
    "notificationid": "7hstyans",
    "notificationtitle": "Some alert title",
    "notificationtype": "SPECIAL ALERT",
    "dateCreated": "1502203175"
}, {
    "notificationid": "9ksh7dh2",
    "notificationtitle": "This is a old notification",
    "notificationtype": "OLD ALERT",
    "dateCreated": "1502138431"
}, {
    "notificationid": "iksnudo3",
    "notificationtitle": "new notification",
    "notificationtype": "SOME ALERT",
    "dateCreated": "1501000523"
}]
}

我正在寻找一种方法来访问它，例如data.notifications[0]["notificationid"]

这会被认为是json的正确格式以及访问它的正确方法还是格式化这种格式的最佳方法？

只需使用json_decode即可。 例如：

$data = json_decode($jsonString, true);
echo $data['notifications'][0]['notificationid'];
