數組賦值的問題

public function setParm($parameter, $value) {$this->parameter[$parameter] = $value;return $this;}function geturl($type){     $this->setproductparm($type);     return $this->getData();     }     private function setproductparm($urltype){     $this->parameter=array();     $this->type="";     $this->setParm("Marketplace",self::marketplaceId);     $this->version="2009-01-01";     switch ($urltype){        case "RequestReport":                $this->setParm("Action","RequestReport");            $this->setParm("ReportType","_GET_MERCHANT_LISTINGS_DATA_");        break;        case "GetReportList":              $this->setParm("Action","GetReportList");               $this->setParm("ReportRequestIdList.Id.1",$this->ReportRequestId);        break;        case "GetReport":              $this->setParm("Action","GetReport");               $this->setParm("ReportId",$this->ReportId);          break;                                   }             }

$url1=$aa->geturl("RequestReport");
$url2=$aa->geturl("GetReportList");
$url3=$aa->geturl("GetReport");

我明明每次執行前都清除了數組
$this->parameter=array();
但輸出時，每次數組都包含了上次所賦的值。
每次結果：
$url1：ReportType=_GET_MERCHANT_LISTINGS_DATA_
$url2：ReportType=_GET_MERCHANT_LISTINGS_DATA_&ReportRequestIdList.Id.1=123456
$url3：ReportType=_GET_MERCHANT_LISTINGS_DATA_&ReportRequestIdList.Id.1=123456&ReportId=123456

請問是哪裡的問題啊？？？

回複討論(解決方案)

你沒有給出 getData 的定義，不好說

//看看是不是下面的方法哪裡處理了getData();
