我有一个数组，看起来像这样：

Array
(
    [0] => 26
    [1] => 644
)
Array
(
    [0] => 20
    [1] => 26
    [2] => 644
)
Array
(
    [0] => 26
)
Array
(
    [0] => 47
)
Array
(
    [0] => 47
    [1] => 3
    [2] => 18
)
Array
(
    [0] => 26
    [1] => 18
)
Array
(
    [0] => 26
    [1] => 644
    [2] => 24
    [3] => 181
    [4] => 8
    [5] => 6
    [6] => 41
    [7] => …

有没有办法隐藏内容添加上无论如何都没有使用的内容元素？
