Need help parsing JSON decoded grandchildren with PHP

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 />";
    } 
}

...to parse this response: http://pastebin.com/uxBF3Kxe# (after I've decoded it).

All the values for ['track']['name'] and ['track']['duration_ms'] are echoed correctly, but nothing is echoed for ['track']['artists']['name'].

What am I doing wrong here?

Thanks!

Answer 1

['track']['artists'] is array :)

Try this ;)

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

Btw... This is better solution ;)

$response_2 = json_decode($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 />";
}

/** Added separator */

$response_2 = json_decode($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 />";
}
