PHP Array Duplicate Value

Question

I have an array like this:

 Array
 (
 [0] => Array
    (
        [0] => Array
            (
                [Foo] => FooBar
            )

    )

[1] => Array
    (
        [0] => Array
            (
                [Foo] => BarFoo
            )
    )

[2] => Array
    (
        [0] => Array
            (
                [Foo] => FooFoo
            )

    )

[3] => Array
    (
        [0] => Array
            (
                [Foo] => FooFoo
            )

    )

)

I basically want to be able to look at [2] and [3] and be able to merge those two together since their values are the same. Basically I just don't want to double count. Is there a simple way of doing this while looping through?

Is this structure always the same? [0] => Array ( [0] => Array ( [Foo] => FooBar ) ) — Arun D, Aug 17 '16 at 18:53
Yes, obviously with different values, but yes same structure! — codnor, Aug 17 '16 at 18:56

You can try this

$unique_array = array_map("unserialize",
      array_unique(array_map("serialize", $your_array)));
