Czesc,
Czy w php jestem w stanie posortowac jakos taka tablice:

[PHP] pobierz, plaintext 
Array (
    [name] => Array
        (
            [0] => 'a'
            [1] => 'b'
            [2] => 'c'
            [3] => 'y'
            [4] => 'k'
        )
 
    [age] => Array
        (
            [0] => 22
            [1] => 23
            [2] => 21
            [3] => 25
            [4] => 24
        )
 
    [bd] => Array
        (
            [0] => 2016-10-25 20:00
            [1] => 2016-10-31 05:00
            [2] => 2016-10-31 23:00
            [3] => 2016-10-31 03:00
            [4] => 2016-10-31 03:00
        )
