以正確的方式重新格式化json-有解無憂

我有這個 php 代碼，因為我試圖在我的 php 專案中執行一個特定的函式，我對實作進行了正確的編碼，但我遇到了一個小問題。

                <?php echo '<script type="text/javascript">';

                $data = array(
                    'base' => 'USD',
                    'alter' => 'ETH',
                    'data' => array()
                );

                foreach ($cryptos as $row) {
                    $sy = $row["symbol"];
                    $data['data'][] = array(
                       "$sy"  => [
                            "rate" => 1.552000000000000,
                            "min" => 1.0077600000000000,
                            "max" => 10.077600000000000,
                            "code" => $row["symbol"],
                            "dp" => 8

                        ],

                    );
                }
                print_r("var fxCur = " . json_encode($data));

運行上面的代碼我得到了下面的結果，這是預期的結果，但我想在資料之間省略 []

{
   "base":"USD",
   "alter":"ETH",
   "data":[
      {
         "BTC":{
            "rate": 1.552000000000000,
            "min": 1.0077600000000000,
            "max": 10.077600000000000,
            "code":"BTC",
            "dp":8
         }
      },
      {
         "ETH":{
            "rate": 1.552000000000000,
            "min": 1.0077600000000000,
            "max": 10.077600000000000,
            "code":"ETH",
            "dp":8
         }
      }
   ]
}

但實際上我想要這個結果

{
   "base":"USD",
   "alter":"ETH",
   "data":{
      "BTC":{
          "rate": 1.552000000000000,
          "min": 1.0077600000000000,
          "max": 10.077600000000000,
         "code":"BTC",
         "dp":8
      },
      "ETH":{
          "rate": 1.552000000000000,
          "min": 1.0077600000000000,
          "max": 10.077600000000000,
         "code":"ETH",
         "dp":8
      },
   
   }
}

uj5u.com熱心網友回復：

您是在告訴它以這種方式構建資料結構。

$data['data'][] = array(
  "$sy"  => [
    ...
  ]
);

該行表示“$data['data']在下一個整數索引處追加一個元素并將其設定為等于陣列，例如[ "BTC" => [ ... ]]

我想你想要的是：

$data['data'][$sy] = [
    "rate" => 1.552000000000000,
    "min" => 1.0077600000000000,
    "max" => 10.077600000000000,
    "code" => $row["symbol"],
    "dp" => 8
];
