如何从Azuracast API json输出中获取PHP数据？

<?php
// Azuracast API端点URL
$apiUrl = 'https://your-azuracast-api-endpoint';

// Azuracast API访问令牌
$accessToken = 'your-access-token';

// 发送GET请求
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $apiUrl);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Authorization: Bearer ' . $accessToken
));
$response = curl_exec($ch);
curl_close($ch);

// 解析JSON响应
$data = json_decode($response, true);

// 获取特定数据
$stationName = $data['station']['name'];
$currentSong = $data['now_playing']['song']['title'];

// 输出数据
echo '电台名称：' . $stationName . '<br>';
echo '当前播放歌曲：' . $currentSong;
?>
