Change Array keys to numeric in PHP

Question

This is probably a simple question for you php whizzes out there but I can't seem to find an answer in google!

I have a multi-dimensional array which first set of keys are named and I want to change them into numbers like 0, 1, 2..

If it was a normal array I could set $newArray = array_values($multiArr); and it would get rid of the keys and make them numeric! But since its multidimensional theres another set of keys/values underneath this.

Could I somehow use a loop to loop through it and define each one? But then how would I specify the current key?

Any advice would help thank you!

If this helps at all the data coming in is a JSON received from a device and there's something wrong with the encoding so the data looks like this:

`Array
(
    [�w� ��߯19�] => Array
        (
            [down] => 1279146141431
            [up] => 1279146351453
        )
`

So I need to somehow get access to the data underneath each crazy key.

This code:

$arr = array(
  'a' => array('a' => '1', 'b' => '2', 'c' => '3'),
  'b' => array('d' => '4', 'e' => '5', 'f' => '6'),
  'c' => array('g' => '7', 'h' => '8', 'i' => '9'),
);
$arr2 = array_values($arr);

yields $arr2 in this form:

[0] => Array
    (
        [a] => 1
        [b] => 2
        [c] => 3
    )

[1] => Array
    (
        [d] => 4
        [e] => 5
        [f] => 6
    )

[2] => Array
    (
        [g] => 7
        [h] => 8
        [i] => 9
    )

Isn't that what you're trying to get?
