关键是array_filter这个函数；例子： 原数组：
Array
(
[0] => Array
(
[ExchangeNo] => ECR000033
[CardNo] => Array
(
)
[QTY] => 1
[ExchangeDate] => 2013-06-13T18:55:23.84
[Remark] => Array
(
)
)
[1] => Array
(
[ExchangeNo] => ECR000036
[CardNo] => Array
(
)
[QTY] => 20
[ExchangeDate] => 2013-06-20T18:24:32.53
[Remark] => Array
(
)
)
[2] => Array
(
[ExchangeNo] => ECR000037
[CardNo] => Array
(
)
[QTY] => 20
[ExchangeDate] => 2013-06-20T18:28:23.14
[Remark] => Array
(
)
)
[3] => Array
(
[ExchangeNo] => ECR000038
[CardNo] => Array
(
)
[QTY] => 20
[ExchangeDate] => 2013-06-20T18:30:53.71
[Remark] => Array
(
)
)
)
去除空数组：
foreach ($array as $key=>$value){
$array[$key] = array_filter($value);
}
输出结果：
Array
(
[0] => Array
(
[ExchangeNo] => ECR000033
[QTY] => 1
[ExchangeDate] => 2013-06-13T18:55:23.84
)
[1] => Array
(
[ExchangeNo] => ECR000036
[QTY] => 20
[ExchangeDate] => 2013-06-20T18:24:32.53
)
[2] => Array
(
[ExchangeNo] => ECR000037
[QTY] => 20
[ExchangeDate] => 2013-06-20T18:28:23.14
)
[3] => Array
(
[ExchangeNo] => ECR000038
[QTY] => 20
[ExchangeDate] => 2013-06-20T18:30:53.71
)
)
