删除由 php unset 创建的数字键

Question

我尝试根据当前日期和时间过滤 json 数据：

我的json是：

{ "responseData": [ { "totalValue": 0.0, "active": "Oct 16, 2019 11:16:23 AM", "expired": "Mar 28, 2020 3:15:58 PM" }, { "totalValue": 0.0, "active": "Oct 16, 2019 11:16:23 AM", "expired": "Mar 28, 2020 3:15:58 PM" }, { "totalValue": 0, "active": "Jun 25, 2019 6:34:59 PM", "expired": "Oct 16, 2020 11:10:32 AM", } ], "responseMessage": "success", "responseCode": 0 }

过滤 php 是：

date_default_timezone_set('UTC'); json_decode($mybalance, true); foreach($json['responseData'] as $key=>$value){ if(strtotime($value['expired']) < strtotime(date('M d, Y H:i:s A'))){ unset($json['responseData'][$key]); } }

在上面的代码中 json 被过滤，响应是

{"responseData":{"2":{"totalValue":0,"active":"Jun 25, 2019 6:34:59 PM","expired":"Oct 16, 2020 11:10:32 AM"}},"responseMessage":"success","responseCode":0}

我的问题是，如何在 json 响应中删除“2”？

我预期的 json 响应是：

{"responseData":{"totalValue":0,"active":"Jun 25, 2019 6:34:59 PM","expired":"Oct 16, 2020 11:10:32 AM"},"responseMessage":"success","responseCode":0}

先像现在一样过滤，然后使用

$json['responseData'] = array_values($json['responseData']);

对数组重新编号。
