Need help parsing JSON decoded grandchildren with PHP - 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 />";
}
