我是php的新手，我不知道如何从对象内部的对象中获取数据，然后是数组，然后是数据，所以我想从php中获取数据。我用过这个
echo "<pre>";
var_dump($res);
echo "</pre>";
获取反对的数据为：
object(stdClass)#1 (1) {
["1"]=>
object(stdClass)#2 (13) {
["childSemCategories"]=>
array(238) {
[0]=>
object(stdClass)#3 (13) {

NULL

在这里我想获取的数据["displayName"]=>
使用get_object_vars（）函数。
$data = get_object_vars($res); // data contain array value
你可以循环$data
foreach($data as $a){
if(!is_array($a)) $a = get_object_vars($a);
foreach($a as $b){
//loop and cek while is object value
}
}
