如何在PHP中比较两个数组值

Question

我有两个功能，第一个是：

   public function computeGHComponents()
    {
      error_reporting (E_ALL^ E_NOTICE);          

      $totals = NULL;

      foreach ($this->transaction as $t){

          $amount = (float) $t['Amount'];



            if (isset($totals[ $t['SiteID'] ][ $t['TransactionType'] ])){
                $totals[ $t['SiteID'] ][ $t['TransactionType'] ] += (float) $amount;
            } else {
                $totals[ $t['SiteID'] ][ $t['TransactionType'] ] = (float) $amount;
            }
        }

     foreach($totals as $key => $value)

        {

         $this->result[$key]['Deposit'] = isset($value['D']) ? $value['D'] : 0;
         $this->result[$key]['Reload']  = isset($value['R']) ? $value['R'] : 0; 
         $this->result[$key]['Redemption'] = isset($value['W']) ? $value['W'] : 0;

       }
    echo "<pre>";

  print_r($this->result);

} 

第二个功能是：

    public function bindOwnerToSites(){

     error_reporting (E_ALL^ E_NOTICE);  

    foreach( $this->balance as $keysaa =>$key_valuesa)//getsitebalance
            { 
                foreach( $this->sites as $keys=>$key_values)//getsites
                  {

                        if  ($key_values['SiteID'] == $key_valuesa['SiteID'])
                        {

                         $this->arrays[$key_valuesa['SiteID']] = array('SiteID'=>$key_valuesa['SiteID'],'Balance'=>$key_valuesa['Balance'],'MinBalance'=>$key_valuesa['MinBalance'],'MaxBalance'=>$key_valuesa['MaxBalance'],'OwnerAID'=>$key_values['OwnerAID'],'GroupID'=>1);    

                        }
                 }

            }
       print_r ($this->arrays,$return=null);  
    }

现在，我需要比较两个SiteID以便进行绑定，这是我的功能：

    public function bindGHComponentsToSites()
    {
    error_reporting (E_ALL^ E_NOTICE);  


     foreach ($this->arrays as $keys => $data) {

        foreach($this->result as $key => $value){


    if ($data['SiteID'] == $value['SiteID']){
            }
     }
 }

我曾经回显SiteID的比较，像这样：

echo（$ data ['SiteID']。'=='。$ value ['SiteID']）;

但是computeGHComponents（）函数的$ value ['SiteID']中没有值，它显示如下：

 2==
 2==
 2==
 3==
 3==
 3==

如何从computeGHComponents（）获取SiteID的值？ 请帮助我修改我的代码。 先感谢您。

我曾经使用print_r我的$ keyss，但发现它是SiteID，所以我像这样修改我的代码：

    public function bindGHComponentsToSites()
    {
   error_reporting (E_ALL^ E_NOTICE);  


     foreach ($this->arrays as $keys => $data) {


       foreach($this->result as $keyss => $value){

         //print_r($keyss );echo '<br/>';

         if($data['SiteID'] == $keyss){

               //statement...
            }
       }
    }
