需要帮助使用PHP解析JSON解码后代

Question

foreach($response_2['items'] as $item) {
$item['track']['name'] = (array)$item['track']['name'];
foreach($item['track']['name'] as $key => $value) {
    echo $value . "<br />";
}
$item['track']['artists']['name'] = (array)$item['track']['artists']['name'];
foreach($item['track']['artists']['name'] as $key => $value) {
    echo $value . "<br />";
} 
$item['track']['duration_ms'] = (array)$item['track']['duration_ms'];
foreach($item['track']['duration_ms'] as $key => $value) {
    echo $value . "<br />";
    } 
}

...以解析此响应： http : //pastebin.com/uxBF3Kxe# （在我解码后）。

正确回显了['track']['name']和['track']['duration_ms']所有值，但没有回显['track']['artists']['name'] 。

我在这里做错了什么？

谢谢！

Answer 1

['track']['artists']是数组:)

尝试这个 ;）

foreach($item['track']['artists'] as $key => $value) {
    echo $value['name'] . "<br />";
}

顺便说一句...这是更好的解决方案;）

$response_2 = json_decode($json, true);

foreach($response_2['items'] as $item) {
    echo $item['track']['name'] . "<br />";

    foreach($item['track']['artists'] as $key => $value) {
        echo $value['name'] . "<br />";
    }

    echo $item['track']['duration_ms'] . "<br />";
}

/ **添加了分隔符* /

$response_2 = json_decode($json, true);

foreach($response_2['items'] as $item) {
    echo $item['track']['name'] . "<br />";

    echo implode(',', array_map(
            function ($value) {
                return $value['name'];
            },
            $item['track']['artists']
        )
    );

    echo "<br />";

    echo $item['track']['duration_ms'] . "<br />";
}
