php如何删除多维数组中的相同值对应键值所有元素如下

例：Array(0 => Array(0 => "a", 1 => 1, 2 => "asd", 3 => "v"), 1 => Array(0 => "b", 1 => 2, 2 => "c", 3 => "c"), 2 => Array (0 => "c", 1 => 3, 2 => "asd", 3 => 123), 3 => Array(0 => "d", 1 => "asd", 2 => 99, 3 => 123))；
获得
Array(0 => Array(0 => "a", 1 => 1), 1 => Array(0 => "b", 1 => 2), 2 => Array(0 => "c", 1 => 3), 3 => Array(0 => "d", 2 => 99))

Answer 1

对于多维数组的话，并且不清楚具体几维的话，那就只能使用foreach配合，递归进行遍历数组了。

以第一个子数组元素作为基础，存在的记录，不存在的加入基础匹配。

Answer 2

最简单的暴力的方式是：多层foreach循环。
