Php 自定义输入数组并将其放入输出

我希望像下面的示例一样处理输入值和复选框，在复选框中的name元素没有更改的情况下，我尝试了以下方法，但这不起作用：

演示：

如果您使用cDA[0][]作为输入框集合的名称，它会将$\u POST['cDA']转换为：

array(
    0 => array(
        0 => 11,
    ),
    0 => array(
        0 => 11,
    ),
    0 => array(
        0 => 33,
    ),
    0 => array(
        0 => 33,
    ),
    0 => array(
        0 => 55,
    ),
    0 => array(
        0 => 55,
    ),
);

使用cDC[]]作为输入框的名称，您将在$\u POST['cDC']中得到此数组：

要使它们正确分组，必须明确设置第一个方括号之间的值：

Array
(
    [cDI] => Array
        (
            [0] => F1
            [1] => F2
            [2] => F3
        )
    [cDA] => Array
        (
            [0] => Array
                (
                    [0] => 11
                    [1] => 11                    
                )
            [1] => Array
                (
                    [0] => 33
                    [1] => 33                    
                )
            [2] => Array
                (
                    [0] => 55
                    [1] => 55                    
                )

        )
    [cDC] => Array
        (
            [0] => Array
                (
                    [0] => 22
                    [1] => 22                    
                )
            [1] => Array
                (
                    [0] => 44
                    [1] => 44                    
                )
            [2] => Array
                (
                    [0] => 66
                    [1] => 66                    
                )

        )

)

array(
    0 => array(
        0 => 11,
        1 => 11,
        2 => 33,
        3 => 33,
        4 => 55,
        5 => 55,
    ),
);

array(
    0 => array(
        0 => 11,
    ),
    0 => array(
        0 => 11,
    ),
    0 => array(
        0 => 33,
    ),
    0 => array(
        0 => 33,
    ),
    0 => array(
        0 => 55,
    ),
    0 => array(
        0 => 55,
    ),
);
