I have this array with data. I'm currently displaying it from my foreach loop as provided, but I want to reorder it (Starting from the MAX id to MIN id)

```
[0] => Array (
    [id] => 1
    [timestamp_start_ex] => Wed Mar  9 18:28:14 2016
    [timestamp_end_ex] => Wed Mar  9 19:28:14 2016

[18] => Array (
    [id] => 19
    [timestamp_start_ex] => Wed Mar  9 00:28:14 2016
    [timestamp_end_ex] => Wed Mar  9 01:28:14 2016
    [timestamp_start] => 1457479694
    [timestamp_end] => 1457483294
    [orders] => 0
    )
[19] => Array (
    [id] => 20
    [timestamp_start_ex] => Wed Mar  9 00:00:00 2016
    [timestamp_end_ex] => Wed Mar  9 00:28:14 2016
    [timestamp_start] => 1457478000
    [timestamp_end] => 1457479694
    [orders] => 0
    )

```

I would like to inverse the array, it means:

```
[0] => id = 19
[1] => id = 18
(...)
[19] => id => 1

```

I tried with `ksort()` but nothing, It does not want to reorganize the Array.
