'undefined offset errors' php 多维数组

Question

我正在尝试获取一个 php 程序来从另一个数组中的数据构建一个多维数组。

$n = 13;
while($n <=22){
    $itemName = $outputFields['FLD_'+ $n +'_002']['value'];
    $itemUM = $inputFields['FLD_'+ $n +'_029']['value'];
    $itemUnits = $inputFields['FLD_'+ $n +'_032']['value'];
    $itemUnitsPrice = $outputFields['FLD_'+ $n +'_045']['value'];
    $itemExtendedPrice = $outputFields['FLD_'+ $n +'_060']['value'];
    $itemLT = $outputFields['FLD_'+ $n +'_076']['value'];
    $arrItems[$itemName][$itemUM][$itemUnits][$itemUnitsPrice][$itemExtendedPrice][$itemLT] = true;
    $n++;   
}

想法最终结果应该是这样的：

Array
(
    [13] => Array
        (
            [itemName]
            [itemUM]
            [itemUnits]
            ...
        )
    ...
    [22] => Array
        (
            [itemName]
            [itemUM]
            [itemUnits]
            ...
        )
)

目前出现 "undefined offset" 个错误。

试试这个代码：

$n = 13;
while($n <=22){
    $arrItems[$n]['itemName'] = $outputFields['FLD_'. $n .'_002']['value'];
    $arrItems[$n]['itemUM'] = $inputFields['FLD_'. $n .'_029']['value'];
    $arrItems[$n]['itemUnits'] = $inputFields['FLD_'. $n .'_032']['value'];
    $arrItems[$n]['itemUnitsPrice'] = $outputFields['FLD_'. $n .'_045']['value'];
    $arrItems[$n]['itemExtendedPrice'] = $outputFields['FLD_'. $n .'_060']['value'];
    $arrItems[$n]['itemLT'] = $outputFields['FLD_'. $n .'_076']['value'];
    $n++;   
}
