Merging of PHP two-dimensional arrays

merge arrays according to field seller_id
Array $result is as follows

Array
(
    [0] => Array
        (
            [seller_id] => 17140
            [bp_counts] => 1
        )

    [1] => Array
        (
            [seller_id] => 17140
            [dr_counts] => 9
        )
    [3] => Array
        (
            [seller_id] => 17140
            [dc_counts] => 10
        )
)

the desired array is

Array
(
    [0] => Array
        (
            [seller_id] => 17140
            [bp_counts] => 1
            [dr_counts] => 9
            [dc_counts] => 10
        )

)
