Question

I am facing Problem with removing the duplicate value from the multidimensional array.

 Array
 (
    [524] => Array
        (
            [0] => 526
            [1] => 530
            [2] => 528
            [3] => 528
        )

    [1100] => Array
        (
            [0] => 1126
            [1] => 1126
            [2] => 1126
            [3] => 1126
        )

    [1244] => Array
        (
            [0] => 1260
            [1] => 1266
            [2] => 1260
            [3] => 1260
