试图在php中创建一个对象数组

我尝试使用以下函数迭代数组：

public static function getDataForChartAlexaDailyRank($data)
{
    $asd = [];
    $new = [];
    $site = [];
    for ($x = 0; $x < sizeof($data->data); $x++) {
        foreach ((array)@$data->data->{$x} as $value) {
            array_push($site, intval($value->{"Response"}->{"TrafficHistoryResult"}->{"Alexa"}->{"TrafficHistory"}->{"Site"}));
        }
        foreach ((array)@$data->data->{$x} as $value) {
            array_push($new, intval($value->{'Response'}->{'TrafficHistoryResult'}->{'Alexa'}->{'TrafficHistory'}->{'HistoricalData'}->{'Data'}->{'Rank'}));
        }
        $asd[] = ['name' => $site, 'data' => $new];
        $new = [];
    }
    return json_encode($asd);
}

阵列如下：

["data"]=>
  object(stdClass)#229 (2) {
    ["mainUrl"]=>
    object(stdClass)#235 (1) {
      ["Response"]=>

数组存储在变量$data中(因此是访问数组的$data数据(，我必须遍历这两个对象(["mainUrl"]和["competitorUrl1"](来获得["Site"]和["Rank"]，并将它们存储到变量$asd中。我编写的函数试图做到这一点。我说尝试是因为我不知道如何正确地遍历不同名称的对象(["mainUrl"]和["competitorUrl1"](。如果我没有很好地解释，我很抱歉，但我是php的一个新手，所以如果你有任何问题，请问。非常感谢您抽出时间。
