看看你可以用这种方式做到

这是给 PHP 人员的:)

    $json='{"period":"","billing_mode":"checked","price":"1500","packageid":0,"name":"hello stack","subscriberid":"9283is3j4","date":"2016-06-23","serviceid":0,"type":"event","programid":999}';

    $arr = json_decode($json, true);
    unset($arr['period']);
    echo json_encode($arr);
