如何使用 json_decode() 解析 PHP 中的 JSON 物件？

{
  "data": {
    "current_condition": [],
    "request": [],
    "weather": [
      {
        "date": "2022-07-28",
        "weatherCode": "113",
        "weatherDesc": [
          {
            "value": "Sunny"
          }
        ],
        "weatherIconUrl": [
          {
            "value": "http:\/\/www.example.com/weather_icons/sunny.png"
          }
        ]
      },
      // More weather data for subsequent days...
    ]
  }
}

$json = '{"data": ... }';  // Assuming the JSON string is stored in $json
$data = json_decode($json, true);

// Accessing the weather data
$weatherData = $data['data']['weather'];

foreach ($weatherData as $weather) {
  echo $weather['date'] . ': ' . $weather['weatherDesc'][0]['value'] . '<br>';
  echo '<img src="' . $weather['weatherIconUrl'][0]['value'] . '" />';
}
