Question

以下是json文件的一部分：

{
  "status": {
     "http_code": 200
  },
  "contents": [
    {
      "FabrikatNavn": "Jaguar",
      "ModelNavn": "420G",
      "PrisDetailDkk": 119900,
      "StatusTyper": [
        {
          "StatusId": -5,
          "StatusNavn": "Benzin"
        },
        {
          "StatusId": -15,
          "StatusNavn": "Momsfri"
        },
        {
          "StatusId": -11,
          "StatusNavn": "100-120.000"
        }
      ],


      "ImageIds": [
        {
          "Id": 79359
        },
        {
          "Id": 79360
        },
        {
          "Id": 79361
        },
        {
          "Id": 79370
        }
      ]
    },
    {
      "FabrikatNavn": "Opel",
      "ModelNavn": "Corsa",
      "PrisDetailDkk": 135900,
      "StatusTyper": [
        {
          "StatusId": -4,
          "StatusNavn": "Diesel"
        },
        {
          "StatusId": -15,
          "StatusNavn": "Momsfri"
        },
        {
          "StatusId": -12,
          "StatusNavn": "120-140.000"
        }
      ],


      "ImageIds": [
        {
          "Id": 225794
        },
        {
          "Id": 225795
        },
        {
          "Id": 225796
        },
        {
          "Id": 225797
        }
      ]
    },
    {
      "FabrikatNavn": "Hyundai",
      "ModelNavn": "H1",
      "PrisDetailDkk": 14999,
      "StatusTyper": [
        {
          "StatusId": 13,
          "StatusNavn": "Afhentning"
        },
        {
          "StatusId": -4,
          "StatusNavn": "Diesel"
        },
        {
          "StatusId": -8,
          "StatusNavn": "0-60.000"
        }
      ],


      "ImageIds": [
        {
          "Id": 415605
        },
        {
          "Id": 415606
        },
        {
          "Id": 415607
        },
        {
          "Id": 415979
        }
      ]
    }
  ]
}

这是PHP

<?php

$url = 'http://banen.klintmx.dk/json/ba-simple-proxy.php?url=api.autoit.dk/car/GetCarsExtended/59efc61e-ceb2-463b-af39-80348d771999';
$json= file_get_contents($url);

$data = json_decode($json);
$rows = $data->{'contents'};
foreach ($rows as $row) {
    echo '<div>';
    $FabrikatNavn = $row->FabrikatNavn;
    $ModelNavn = $row->ModelNavn;
    $PrisDetailDkk = $row->PrisDetailDkk;

    // tried this, but it don't work -->
    foreach($row->StatusTyper as $StatusTyper) {
        $StausId = $StatusTyper->StatusId;
        if ($StausId == '-15') { $Moms = 'mm'; }
        else { $Moms = 'um'; }
    }

    echo '<div class=" ' . $Moms . ' "> ';
    echo $FabrikatNavn . $ModelNavn . ' Pris ' . $PrisDetailDkk;
    echo '</div>';
    echo '</div>';
}

正如你所看到的，“StatusTyper”中的值不同，所以在这里我尝试了if else，但我无法让它工作 - 它每次都返回''' 怎么了？

这是因为循环总是选择最后一个条件的值。如果找到匹配项$StausId == "-15"，您需要以某种方式告诉PHP break循环，否则它将继续匹配$StausId != "-15"，它始终将值"um"赋给$Moms }。

foreach($row->StatusTyper as $StatusTyper) {
    $StausId = $StatusTyper->StatusId;

    if ($StausId == "-15") {
        // Found the match
        $Moms = 'mm';
        // End the execution of current loop
        break;
    } else {
        // $StausId value is not equal to -15
        // So it was picking this
        $Moms = 'um';
    }

}

PHP foreach - 从数组内的数组中解析json
