使用 php 从 json 获取特定值

Question

我只需要从一个键中获取特定的值，例如：

我需要从

获取"odd": "6.25"的值

"name": "Team To Score Last"->"value": "No goal"

和奇数

这是我的json

"response": [
    {
    "league": {},
    "fixture": {},
    "update": "2020-05-15T09:49:32+00:00",
    "bookmakers": [
        {
        "id": 6,
        "name": "Bwin",
        "bets": [
            {}, {}, {}, {}, {}, {}, {},
            {}, {}, {}, {},
            {    
                "id": 15,
                "name": "Team To Score Last",
                "values": [
                        {
                            "value": "No goal",
                            "odd": "6.25"
                        }

我试过

$odds =json_decode($responseodds, true);
$value=$odds['response'][0]['bookmakers'][0]['bets'][0]['name'];

不幸的是我只得到值最后得分的球队

Answer 1

$json = '{
  "response": [
    {
      "league": {},
      "fixture": {},
      "update": "2020-05-15T09:49:32+00:00",
      "bookmakers": [
        {
          "id": 6,
          "name": "Bwin",
          "bets": [
            {},
            {},
            {},
            {},
            {},
            {},
            {},
            {},
            {},
            {},
            {},
            {
              "id": 15,
              "name": "Team To Score Last",
              "values": [
                {
                  "value": "No goal",
                  "odd": "6.25"
                }
              ]
            }
          ]
        }
      ]
    }
  ]
}
';

$data = json_decode($json, true);
echo "<pre>";
var_dump($data);
echo "<pre>";

$bets = $data['response'][0]['bookmakers'][0]['bets'];

foreach ($bets as $item) {
    if (empty($item)) {
        continue;
    }

    $odd = $item['values'][0]['odd'];

    var_dump($item);
    var_dump($odd);
}

我试过了，结果是奇数

遍历投注数组，寻找您感兴趣的投注 name。

foreach ( $odds['response'][0]['bookmakers'][0]['bets'] as $bet){
    if ( $bet['name'] == "Team To Score Last") {
        // this is the one
        echo 'The odds were ' . $bet['values'][0]['odd'];
    }
}

如果您想要所有博彩公司的这些赔率

foreach ( $odds['response'][0]['bookmakers'] as $bookie){

    foreach ( $bookie as $bet){
        if ( $bet['name'] == "Team To Score Last") {
            // this is the one
            echo 'The bookie ' . $bookie['name'] . 'has the odds ' . $bet['values'][0]['odd'];
        }
    }
}
