我想从数组中的数组中提取数据。但问题是，当我使用 key 功能时，它会覆盖第一个条目。我希望得到 135 行的结果，但它只给我 114 行。

下面是我遇到问题的代码..

while($row1 = mssql_fetch_array($result1)) {
        $mycount = $mycount + 1;
        $boskey = $row1["EAN11"]."^".$row1["AUART"];
        $boskey1 = $row1["ORDNUM"]."^".$row1["ERDAT"]."^".$row1["KUNAG"]."^".$row1["NAME1"]."^".$row1["PERNR"]."^".$row1["FKIMG"]."^".$row1["BASEPRICE"]."^".$row1["NETPRICE"]."^".$row1["ZZMAXDISC"]."^".$row1["MVGR1"]."^".$row1["KDGRP"];
        $bos[$boskey][$boskey1] = $bos[$boskey][$boskey1];

    }

        for ($i = 0; $i < count($bos); $i++) {
            $abc = key($bos);   

            $arr = explode("^",$abc);
            $ean11 = $arr[0];
            $auart = $arr[1];

            echo $ean11 . " - " . $auart;

            for ($j = 0; $j < count($bos[$abc]); $j++) { //total count of $bos[$abc] is 114.
                $xxx = key($bos[$abc]);
                $arr1 = explode("^",$xxx);

                $ordnum = $arr1[0];
                $docdate = $arr1[1];
                $customer = $arr1[2];
                $name1 = $arr1[3];
                $ae = $arr1[4];
                $qty = $arr1[5];
                $baseprice = $arr1[6];
                $netprice = $arr1[7];
                //$discount = $arr1[8];
                $booktype = $arr1[9];
                $kdgrp = $arr1[10];
                $discount = 100 - (100 * ( $netprice / $baseprice));
