変数配列をリセット

foreach($arr as k1=>$v1){			$sql2 = "select cust_no,total=SUM(mount)*snp from ".$t." where po_num = '".$stockno."' and cust_no = '".$v1['cust_no']."' group by cust_no,snp";				$result2 = mssql_query($sql2);			$b = array();			while($row2 = mssql_fetch_array($result2))			{				$b[] = $row2;			}									foreach($b as $var)			{				$num = $var['total'];				foreach($a as $i=>$dest)				{					if($num == 0)						break;					if($dest['cust_no'] != $var['cust_no'])						continue;					if($num >= $dest['part_count'])					{						$num -= $dest['part_count'];						$ress[] = $dest;						$a[$i]['part_count'] = 0;					}					else					{						$dest['part_count'] = $num;						$ress[] = $dest;						$a[$i]['part_count'] -= $num;						$num = 0;					}				}			}			print_r($ress);}

変数配列 $ress をリセットするにはどうすればよいですか? unset() を使用しても効果はありません。

対応する SQL 条件と配列 $b の値:

col1:select cust_no,total=SUM(mount)*snp from dfl_stock_detail where po_num = 'SU14031300627' and cust_no = '237033AW0A' group by cust_no,snpArray ( [0] => Array ( [0] => 237033AW0A [cust_no] => 237033AW0A [1] => 375 [total] => 375 ) )col2: select cust_no,total=SUM(mount)*snp from dfl_stock_detail where po_num = 'SU14031300627' and cust_no = '237033RC3A' group by cust_no,snpArray ( [0] => Array ( [0] => 237033RC3A [cust_no] => 237033RC3A [1] => 75 [total] => 75 ) )

$b の異なる値に従って、対応する $ress の値を見つけます。

しかし、$ress が計算されると、col2 は依然としてcol1 の結果になります。

unset が利用可能であるはずです。その unset で何かを出力して、何が起こるかを確認してください。

Array a配列 a の cust_no の合計が配列 b の cust_no の合計と一致する場合、配列 b と一致します。 $ress を必要とする同様の結果は次のとおりです:

Array(    [0] => Array        (            [cust_no] => 237033AW0A            [lotno] => 4409            [part_count] => 300        )    [1] => Array        (            [cust_no] => 237033AW0A            [lotno] => 4410            [part_count] => 75        )    [2] => Array        (            [cust_no] => 237033RC3A            [lotno] => 4418            [part_count] => 75        ))

これは可能ですか?あるいは、1# のようなループに入れて、配列 b の値が であるとき、対応する配列 a の一致結果は何ですか? $ress 値を割り当てた後にリセットするにはどうすればよいですか?

ということですか？それともさらに要件がありますか?

私の #6 は要件を満たしていませんか?
$b をグループで扱う場合、
foreach($b as $d) {

$b の結果を満たすために $a を減算する必要があります。例:

$ress の結果

Array ( [0] => Array ( [cust_no] => 237033AW0A [lotno] => 4409 [part_count] => 300 ) [1] => Array ( [cust_no ] => 237033AW0A [lotno] => 4410 [part_count] => 75 ) )

$b を満たす結果
array ( 'cust_no' => '237033AW0A', ' total' = > 375, ), )

私の #6 は要件を満たしていませんか?

$b をグループで扱いたい場合は、

foreach($b as $d) {

私の #6 は要件を満たしていませんか?

$a と $b の cust_no フィールドが同じ場合に、$b の合計を満たす $a のpart_count の数を求めたい場合、どのようにその数を求めますか?

但是只能求得$b中第一个一维数组的结果集。
