How can I compute the intersection of an unknown number of arrays in php?

Question

I have an array of arrays, and I want to find the intersection of the contained arrays.

My problem is that the array_intersect function requires the arrays to be explicitly specified in the params. I cannot feed the function with my array-of-arrays.

What can I do?

Array
(
    [0] => Array
        (
            [0] => 1
            [1] => 1504
            [2] => 2181
            [3] => 488
            [4] => 554
            [5] => 1539
            [6] => 494
            [7] => 2022
        )

    [1] => Array
        (
            [0] => 51
            [1] => 617
            [2] => 651
            [3] => 788
            [4] => 799
            [5] => 835
            [6] => 863
            [7] => 407
            [8] => 650
            [9] => 783
        )

)
