toc: true

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
        )
)
