php双重循环问题

我想用php输出我在网易云音乐的歌单内容，先使用一个foreach输出歌单名称和id，再使用上一次输出的id来输出歌单内容。但是输出歌单内容就不知道该怎样写了...求大神帮助

<code><?php header('Content-type: application/json');
            header("Content-type: text/html; charset=utf-8");
            $refer = "http://music.163.com/";
            $header[] = "Cookie: " . "appver=1.5.0.75771;";
            $url = "http://music.163.com/api/user/playlist/?offset=0&limit=1001&uid=52792247";
            $ch = curl_init();
            curl_setopt($ch, CURLOPT_URL, $url);
            curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
            curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
            curl_setopt($ch, CURLOPT_REFERER, $refer);
            $cexecute = curl_exec($ch);
            curl_close($ch);
            $obj = json_decode($cexecute);
            $result = $obj->playlist;
            foreach($result as $row){
            echo $row->name;
            echo $row->id;
            echo $row->coverImgUrl;
            }
?></code>

上面的代码可以正常输出，在有多个id的情况下该怎样循环输出http://music.163.com/api/playlist/detail?id=刚刚输出的id的内容？

又是你!!!

获取用户歌单列表的API是POST请求,且参数做了加密,参考这里,这里就不深入了

<code><?php set_time_limit(0);
$getUserPlayListUrl = 'https://music.163.com/eapi/batch';
$playList = getUserPlayList($getUserPlayListUrl);
$obj = json_decode($playList);
if ($obj->code != 200) {
    exit('fetch user play list fail');
}
$list = $obj->{'/api/user/playlist/'}->playlist;
if (! count($list)) {
    exit('play list is empty');
}
echo "<ul>";
foreach ($list as $row) {
    echo "<li>";
    echo $row->name;
    if ($row->trackCount > 0) {
        $url = 'http://music.163.com/api/playlist/detail?id=' . $row->id;
        $json = file_get_contents($url);
        $obj = json_decode($json);
        
        if (! is_object($obj) || $obj->code != 200) {
            echo ('fetch data fail');
        } else {
            $result = $obj->result;
            if (count($result->tracks)) {
                echo "<ol>";
                foreach ($result->tracks as $key => $item) {
                    echo "<li><a href="%5C%22%24item-">mp3Url\">" . $item->name . "</a></li>";
                }
                echo "</ol>";
            }
        }
    }
    echo "</li>";
}
echo "</ul>";
