php双重循环问题

Question

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

<?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;
            }
?>

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

<?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 => $item) {
                    echo "<li><a href=\"$item->mp3Url\">" . $item->name . "</a></li>";
                }
                echo "</ol>";
            }
        }
    }
    echo "</li>";
}
echo "</ul>";

function getUserPlayList($getUserPlayListUrl)
{
    $post = 'params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
