PHP推送到數組問題

Question

我正在嘗試構建一個數組，然后遍歷它，但不斷出現未定義的索引錯誤。 我在這里做錯了什么？ 陣列構建不正確嗎？ 如果我不將新項目放入其中，則代碼可以正常工作。 一旦向其中添加更多元素，整個過程就會破裂。

foreach($CustPOIDs as $key => $val){
                    $CustPOID = $val['CustPOID'];
                       //Call this method for each CustPOID
                    $tender = new BOL($CustPOID);
                    $pickUpData[]=$tender->getPickupInfo();
                }
            }

           foreach ($pickUpData as $key => $val) {
                $LoadDate = $val['POLineLoadDate'];
                $POLineComments = $val['POLineComment'];
                $ProdID = $val['ProdID'];
                $ShipperId = $val['ShipperId'];
                $ShipDesc = $val['Description'];
                $shAddress = $val['Address1'];
                $shState = $val['State'];
                $shPhone = $val['Phone'];
                $pdProdDesc = $val['ProdDesc'];
                $pdCommodity = $val['Commodity'];
                $pdWeight = $val['ProdWeight'];
            }

似乎數組有一個多余的層次被忽略了……也許嘗試這樣的事情：

for ($i = 0; $i < count($pickUpData); $i++) {
  foreach ($pickUpData[$i] as $key => $val) {
    $LoadDate = $val['POLineLoadDate'];
    $POLineComments = $val['POLineComment'];
    $ProdID = $val['ProdID'];
    $ShipperId = $val['ShipperId'];
    $ShipDesc = $val['Description'];
    $shAddress = $val['Address1'];
    $shState = $val['State'];
    $shPhone = $val['Phone'];
    $pdProdDesc = $val['ProdDesc'];
    $pdCommodity = $val['Commodity'];
    $pdWeight = $val['ProdWeight'];
  }
}
