从客户端基于php中的UTC时间戳对JSON数据进行排序

I have a JSON with some data. One of the fields is a timestamp. Is there any way to sort the data based on the timestamp? Please don't recommend me any jQuery plugins like DataTables. And I don't want to fetch the data from the database in sorted order either. I use the following SQL command.

select * from tablename;

I don't want to get the data in sorted form from database by using a command something like this.

select * from tablename ORDER BY.....

Is it possible to sort JSON data like what I've said using PHP??? I want the data to be sorted in the descending order based on the timestamp. Any suggestions???

Here is a sample data

http://codepad.viper-7.com/TyLOWV

I tried this...

function sortByYear($a, $b) {
    $dA = new DateTime($a['date']);
    $dB = new DateTime($b['date']);

    return $dA->format('y') - $dB->format('y');
}


$d = json_decode($sample_data, true);
$info = $d['date'];

usort($info, 'sortByYear');

print_r($info);

    Try with array_multisort function in PHP

    $date = array();
    $d = json_decode($sample_data, true);
    foreach ($d as $key => $row)
    {
        $date[$key] = $row['date'];
    }
    array_multisort($date, SORT_DESC, $d);
