remove duplicate array from multi dimensional array by key value

Question

i have the following array

 Array
 (
[0] => Array
    (
        [id_scheduled_work] => 238
        [id_schedule_hours] => 1
        [id_truck] => 1
        [id_scheduled_work_details] => 209
        [work_order] => Z20160807211621

    )

[1] => Array
    (
        [id_scheduled_work] => 239
        [id_schedule_hours] => 2
        [id_truck] => 1
        [work_order] => Z20160807211621

    )
[2] => Array
    (
        [id_scheduled_work] => 240
        [id_schedule_hours] => 1
        [id_truck] => 1
        [id_scheduled_work_details] => 209
        [work_order] => A20160807211621

    )

[3] => Array
    (
        [id_scheduled_work] => 245
        [id_schedule_hours] => 2
        [id_truck] => 1
        [work_order] => A20160807211621

    )

  )

So i want to remove duplicate entires by work_order number so my final array should be and i also need to reset the keys so that they go 0 1 ...

  Array
 (
[0] => Array
    (
        [id_scheduled_work] => 238
        [id_schedule_hours] => 1
        [id_truck] => 1
        [id_scheduled_work_details] => 209
        [work_order] => Z20160807211621

    )
[1] => Array
    (
        [id_scheduled_work] => 240
        [id_schedule_hours] => 1
        [id_truck] => 1
        [id_scheduled_work_details] => 209
        [work_order] => A20160807211621

    )

)

i looked at that but that seems to just move anything thats duplicated i need to specifically remove duplicates with work order only that match each other — Yeak, Aug 08 '16 at 05:04

$key = array_column(array, 'work_order');

$result = array_combine($keys, array);
