Resolved Merge child array values (tricky q)

[benwiggy]

Hi guys, trying to think of an elegant way of achieving the following:

- merge the "availability_" elements where the "flight_number" matches
- So that there is only one child array for each flight number (i.e. delete any further child arrays after the merge)
- Note: There won't be an occurrence where there are conflicting "availability_" values for the same flight number

FYI, if it would be easier if "availability" was a child array instead of separate elements, we can do that instead.

Thank you in advance for your help!

E.g. Turn this:

Array
(
    [0] => Array
        (
            [flight_number] => BA0179
            [availability_first] => 
            [availability_business] => 
            [availability_economy] => 99
        )
    [1] => Array
        (
            [flight_number] => BA0213
            [availability_first] => 
            [availability_business] => 
            [availability_economy] => 6
        )
    [2] => Array
        (
            [flight_number] => BA0179
            [availability_first] => 
            [availability_business] => 1
            [availability_economy] => 
        )
)

Into:

Array
(
    [0] => Array
        (
            [flight_number] => BA0179
            [availability_first] => 
            [availability_business] => 1
            [availability_economy] => 99
        )
    [1] => Array
        (
            [flight_number] => BA0213
            [availability_first] => 
            [availability_business] => 
            [availability_economy] => 6
        )
)
