请教一下php的问题

朔朔

小白请教一下，php怎么用foreach获取TrafficUsed的值
代码如下：

{"TotalCount":1,"InstanceTrafficPackageSet":[{"InstanceId":"123-123","TrafficPackageSet":[{"TrafficPackageId":"123-1234","TrafficUsed":1103114770439,"TrafficPackageTotal":1099511627776,"TrafficPackageRemaining":0,"TrafficOverflow":3603142663,"StartTime":"2021-04-24T11:59:42Z","EndTime":"2021-05-24T11:59:41Z","Deadline":"2022-03-24T11:59:43Z","Status":"OVERDUE_NETWORK_DISABLED"}]}],"RequestId":"1-2-3-4"}

不用PHP好久了，python golang 我还可以说两句

安好

$array = json_decode("上面的字符串",true);  这样变成数组 。数组总知道怎么循环了吧

好像是个JSON

1. {
   
2.     "TotalCount": 1,
   
3.     "InstanceTrafficPackageSet": [
   
4.     {
   
5.         "InstanceId": "123-123",
   
6.         "TrafficPackageSet": [
   
7.         {
   
8.             "TrafficPackageId": "123-1234",
   
9.             "TrafficUsed": 1103114770439,
   
10.             "TrafficPackageTotal": 1099511627776,
    
11.             "TrafficPackageRemaining": 0,
    
12.             "TrafficOverflow": 3603142663,
    
13.             "StartTime": "2021-04-24T11:59:42Z",
    
14.             "EndTime": "2021-05-24T11:59:41Z",
    
15.             "Deadline": "2022-03-24T11:59:43Z",
    
16.             "Status": "OVERDUE_NETWORK_DISABLED"
    
17.         }]
    
18.     }],
    
19.     "RequestId": "1-2-3-4"
    
20. }

1. <?php
   
2. $json = '{"TotalCount":1,"InstanceTrafficPackageSet":[{"InstanceId":"123-123","TrafficPackageSet":[{"TrafficPackageId":"123-1234","TrafficUsed":1103114770439,"TrafficPackageTotal":1099511627776,"TrafficPackageRemaining":0,"TrafficOverflow":3603142663,"StartTime":"2021-04-24T11:59:42Z","EndTime":"2021-05-24T11:59:41Z","Deadline":"2022-03-24T11:59:43Z","Status":"OVERDUE_NETWORK_DISABLED"}]}],"RequestId":"1-2-3-4"}';
   
3. $json = json_decode($json, true);
   
4. echo $json["InstanceTrafficPackageSet"][0]["TrafficPackageSet"][0]["TrafficUsed"];
   
5. ?>

json转数组，直接输出数据的键值就好啦

MJJ热心人还是挺多额

Mr.Bean

多层嵌套判断 key就行

clcavril

直接json decode选择那个变量对应的值就好了
