如何在多维PHP中创建键和绑定数组值

我在这里有数据：

这是我的第一个函数的结果。我用于结果的变量是$this->数组。

Array
(
[1] => Array //Transactiondetails of SiteID 1
    (
        [SiteID] => 1
        [Balance] => 2000
        [MinBalance] => 1000
        [MaxBalance] => 500
        [OwnerAID] => 1
        [GroupID] => 1
        [Deposit] => 10000
        [Reload] => 0
        [Redemption] => 0
    )
  )

现在，这是我的第二个函数的结果。我用于结果的变量是$this->组合。

Array
(
[0] => Array
    (
        [AID] => 1
        [Sites] => Array
            (
                [0] => 1 //List of SiteID owned by AID                   
                [1] => 5
            )
    )
[1] => Array
    (
        [AID] => 3
        [Sites] => Array
            (
                [0] => 4 //SiteID
            )
    )
[2] => Array
    (
        [AID] => 4
        [Sites] => Array
            (
                [0] => 1 //SiteID
            )
    )
 )

我用这个代码试试：

 public function createListOfCorpOwnedSites()
 {
 foreach ($this->combined as &$site) {
            $aids = array();
            foreach ($this->result_array as $acct) {
              if ($acct['SiteID'] === $site['SiteID'])
                $aids[] = $acct['AID'];
              }
              $site['CorpAID'] = $aids;
            }
            print_r($this->combined );
            }

但是，我需要一个更好的结果，第一个，我需要添加CorpAID的密钥，指向多个AID拥有的SiteID的列表。

结果应该是这样的：

 Array([0]=> Array(
        [SiteID] => 1
        [Balance] => 2000
        [MinBalance] => 1000
        [MaxBalance] => 500
        [OwnerAID] => 1
        [GroupID] => 1
        [Deposit] => 10000
        [Reload] => 0
        [Redemption] => 0
        [CorpAID] => Array(
                      [0] => 1
                      [1] => 4 
    )

有可能做到吗？请以适当的方式引导我，我感谢你的关心，并提前感谢你。
