将变量数组重置

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);}

如何把变量数组$ress重置?用了unset()还是没有效果。

对应的sql条件及数组$b的值：

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 ) )

按照$b值的不同求对应的$ress的值。

但是现在$ress求出来,col2还是col1的结果。

unset 应该是可以用的 你看哈程序是不是跑到那个unset了 ，在那个unset处输出点东西看看，有啥子反映

数组a与数组b匹配，当数组a的cust_no和数量满足数组b的cust_no和数量时。需要$ress求得的类似结果如下：

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        ))

这样的话可否实现？或者放在如1#的循环中，当数组b值为多少时，对应的数组a的匹配结果为多少？$ress值被赋值后如何重置？

我 #6 的不符合你的要求吗？
如果是要对 $b 分组对待，则
foreach($b as $d) {
$res = array();

我 #6 的不符合你的要求吗？
如果是要对 $b 分组对待，则
foreach($b as $d) {
$res = array();

需要对$a进行减处理，以满足$b的结果。例如：
$ress的结果
Array ( [0] => Array ( [cust_no] => 237033AW0A [lotno] => 4409 [part_count] => 300 ) [1] => Array ([cust_no] => 237033AW0A [lotno] => 4410 [part_count] => 75 ) )
满足$b的结果
array ( 0 => array ( 'cust_no' => '237033AW0A', 'total' => 375, ), )

我 #6 的不符合你的要求吗？
如果是要对 $b 分组对待，则
foreach($b as $d) {
$res = array();

我 #6 的不符合你的要求吗？

如果是求当$a和$b的cust_no字段相同时，$a的part_count的数量满足$b的total的数量怎么求？

我 #6 的不符合你的要求吗？

和这个问题类似。不过$b变成了多维数组。

在那个帖子中 $b 也是多维数组

在那个帖子中 $b 也是多维数组

但是只能求得$b中第一个一维数组的结果集。

这个意思？
