我需要做的是从"洪流"项目中删除，每个项目都有"质量=720p"。
我试过这样的东西：
$data= json_decode($a, true);
//Loop through the array contained in the 'torrents' object.
foreach ($data['data']['movies'] AS $key => $value) {
// Assess the value of the 'quality' object
foreach ($value['torrents'] AS $key2 => $value2) {
if ($value2['quality'] == "720p"){
echo $value2['quality'];
unset($value['torrents'][$key2]);
}
}
}
$data= json_encode($data);
echo $data;
但是由于这个JSON有2个以上的维度，我不知道如何实现它。
我该怎么做？
问候，
数组中包含720p的部分实际上是由｛｝定义的对象，而数组是[]。应该起作用的是：
$data= json_decode($json, true);
//Loop through the array contained in the 'torrents' object.
foreach ($data->torrents AS $value) {
// Assess the value of the 'quality' object
if ($value->quality == "720p"){
unset($value->quality);
}
}
附言，以后我可以建议您简化示例数据，并正确格式化以提高可读性吗。
