我有一个表单，它通过Jquery Ajax Call将数据发送到控制器函数，该函数处理数据，然后从第三方API获取响应。
数据通过POST发送到控制器，然后这些数据通过Curl发送到第三方API，然后以字符串形式返回，然后转换为数组，最后进行json编码。
我遇到了能够使用“echo json_encode（$ array）;”发回数组的地方，但我似乎无法弄清楚如何使用数组。
我想要最终做的是，如果数组上的“结果”键=“失败”，那么我会向div添加一条消息，如果它等于“result”=“success”，那么我会追加消息并运行第二个函数。
返回的响应数组是：
的 {"transaction_id":"8267_03-01-12_16:02:58_0","action":"payment","result":"failed","errors":"98","errors_meaning":"(98)","customer_errors_meaning":"","processing_time":"0.0117"}
