Question

我想知道是否有人可以帮忙。我有一个来自API的JSON提要，我永远无法弄清楚获得所需信息的级别吗？

JSON低于

{
  "sourceId": "1234",
  "sourceType": "MONITOR",
  "searchMeta": {
    "startTimestamp": 1462361513,
    "endTimestamp": 1462508560,
    "maxResults": 10000,
    "metricType": [
      "clients"
    ],
    "family": [
      "Product"
    ],
    "metricsInterval": "M5"
  },
  "clients": {
    "One": [
      {
        "timestamp": 1462361400,
        "avg": 2,
        "min": 1,
        "max": 3,
        "probes": 6,
        "samples": 3,
        "sources": [
          "123",
          "234",
          "345",
          "456",
          "567",
          "789"
        ]
      },

我想将Probes值和Samples值变为变量

foreach($json['clients'] as $range => $product){

echo $product['timestamp']." Probes: ".$product['probes']." Samples: ".$product['samples']." <br>";

}

提前致谢

Answer 1

我假设您有一系列客户端（因此循环）。因此，您需要循环每个客户端，因为它是array object的{{1}}。

如果您想象它，它看起来像这样：

CLIENTS = ARRAY(
    1 => ARRAY( OBJECT{} ), // you want the OBJECT{}
    ....etc
)

因此，下面的循环将为您提供。

$data = json_decode($json, TRUE);

foreach($data['clients'] as $range => $product) {
    foreach($product as $element){
        echo $element['timestamp']." Probes: ".$element['probes']." Samples: ".$element['samples']." <br>";    
    }
}

Example/Demo

返回以下内容：

1462361400 Probes: 6 Samples: 3 <br>

Answer 2

OP的要求：

我想把Probes值和Samples值变成a 变量

简单地将您的json文件命名为$json。

$arr = json_decode($json);

echo $samples = $arr->clients->One[0]->samples; //3
echo $probes = $arr->clients->One[0]->probes; //6

Answer 3

试试这个。

$data = json_decode($json,true);
foreach($data['clients'] as $client){

echo $client['timestamp']." Probes: ".$client['probes']." Samples: ".$client['samples']." <br>";

}

PHP特定JSON数组嵌套级别混淆
