使用PHP计算基于JSON数组中的出生日期信息的一个年龄

I was wondering how I could use PHP to calculate one's age given a date string with values from a JSON array: 

{  
    "DOB":{ // should I use integers or strings for these values? I'm assuming strings for now.  
        "year": "1970",  
        "month": "01",  
        "day": "01"  
    }  
}

How would I then use PHP to calculate the age?
Additionally, say all of this information is a small part of something like a staff directory, with the format of { "People":{ "user1":{ label: value },"user2":{ label: value} } }. How could I use PHP to create <label> tags for label within <li> tags for value (<li><label>label</label>value</li>) within unordered lists for each user within divs for each user?
Please tell me if this is confusing; and the calculation of the age is my highest priority right now.

    Not sure if I correctly understood what you're trying to do with the user so let me know if i was mistaken:

    <?php
    $people = json_decode($data);
?>
<html>
    <head>
        <title>Users List</title>
    </head>
<body>
    <?php foreach ($people as $userName => $userInfo): ?>
    <div>
        <p><?php echo $userName; ?>
        <ul>
        <?php foreach ($userInfo as $label => $value): ?>
            <li><label><?php echo $label; ?></label> <?php echo $value; ?></li>
        <?php endforeach; ?>
        </ul>
    </div>
    <?php endforeach; ?>
</body>
</html>
