PHP从最高到最低排序JSON

Question

我有以下json:

     {
    "ID":"4",
    "name":"Gil",
    "likes":0,
    "Dec":"A Man"
    },
    {
   "ID":"3",
    "name":"Yoni",
    "likes":3,
    "Dec":"A child"
    },
    {
    "ID":"6",
    "name":"Roni",
    "likes":1,
    "Dec":"A woman"
    }

我想基于从最高到最低的喜欢重新排列它,结果将是:

{
        "ID":"5",
        "name":"Roni",
        "likes":6,
        "Dec":"A woman"
        } ,  
   {
       "ID":"3",
        "name":"Yoni",
        "likes":3,
        "Dec":"A child"
        },

 {
        "ID":"4",
        "name":"Gil",
        "likes":0,
        "Dec":"A Man"
        }

我怎样才能在php中重新排列它？

Answer 1

json_decode/ json_encode和usort:

$array = json_decode($json_string, TRUE);

usort($array, function($a, $b) {
    return $a['likes'] - $b['likes'];
});

echo json_encode($array, JSON_PRETTY_PRINT);
