JSON Array of Associative Arrays structure

Question

Im not sure if this would be considered proper format of a json structure. Essentially what Im trying to have is an array of associative arrays. My json data:

{
"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"
}]
}

I am looking for a way to access it such as data.notifications[0]["notificationid"]

Would this be considered the correct format for json and the correct way to access it or what would be the best approach to format this?

If you want to know if you have valid JSON, just check it in JSONLint. And if you want to know if a certain way of doing something works, try it yourself. When you run what you suggested, does it work? Yes? Well, there's your answer. — Patrick Q

read about json_decode , either to associative array, or to stdClass. But : not both as you have it here. Pick one, decode your json, then use the appropriate syntax for the decode-style you picked. — YvesLeBorg

Just use json_decode. Example:

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

Usually "json_decode" decodes the json_string into an object. What "true" param does here is that it outputs the json_string into an associative array.
