如何使用PHP使用API json来预测数据，在这里我提到我使用的API数据样本和我正在尝试的代码，但它不打印任何东西，也没有错误。更新：下面我更新了api数据，以便更好地了解哪些是私有数据，这样我就不会分享api url。

这是代码：

{
  "1": {
    "ID_PP": [
      "1",
      "2",
      "3"
    ],
   "detail": {
      "price": 16.5,
      "tax": null,
      "shipment": null
   }
  },
  "2": {
    "ID_PP": [
      "6",
      "7",
      "8",
      "9",
      "10"
    ],
  "detail": {
    "price": 14,
    "tax": null,
    "shipment": null
   }
  },
  "3": {
    "ID_PP": [
      "13",
      "14"
    ],
    "detail": {
      "price": 6,
      "tax": null,
      "shipment": null
    }
  }
}

$url = "API URL";
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL,$url);
$execute=curl_exec($ch);
curl_close($ch);
$return = json_decode($execute, true);
$i = 0;
foreach($return['ID_PP'] as $key=>$val) {
    echo $val[$i];
$i++;}

这将遍历整个Object并输出您需要的值

$execute = '{
  "1": {
    "ID_PP": ["1","2","3" ],
   "detail": {
      "price": 16.5,
      "tax": null,
      "shipment": null
   }
  },
  "2": {
    "ID_PP": ["6","7","8","9","10"],
  "detail": {
    "price": 14,
    "tax": null,
    "shipment": null
   }
  },
  "3": {
    "ID_PP": ["13","14"],
    "detail": {
      "price": 6,
      "tax": null,
      "shipment": null
    }
  }
}';

$return = json_decode($execute);
print_r($return);

foreach($return as $arrItem){
    foreach($arrItem->ID_PP as $key=>$val){
        echo $val.',';
    }
}

结果

1,2,3,6,7,8,9,10,13,14,
