Multidimensional array sorting

[mark_kccs]

Hi all

I have a multidimensional array that may contain one or many array elements and I need to filter the arrays to find all common values that exist across all the arrays. For example:

Array
(
    [0] => Array
        (
            [0] => Array
                (
                    [0] => 1
                    [1] => 2
                    [2] => 3
                    [3] => 4
                )

        [1] => Array
            (
                [0] => 1
                [1] => 3
                [2] => 5
                [3] => 6
            )

        [2] => Array
            (
                [0] => 1
                [1] => 3
                [2] => 4
                [3] => 7
            )

    )
)

What I want is an array with just the values 1 and 3.

Many thanks

[man]array_intersect[/man] should do what you need. Example here: https://3v4l.org/CPnDB
