How to reverse array in PHP?

I have the following array:

Array ( [2294] => 1 [2292] => 1 [2296] => 1 )

How can I reverse it to 

Array ( [2296] => 1 [2292] => 1 [2294] => 1 )

TRIED array_reverse() but didn't work. What I am missing?

$array = array_reverse($array); // did not work

EDIT: I do not want numeric (order sort) I just need to reverse bottom keys to top, and vice versa

Yes You can do it by krsort in php. As you need to sort based on key

    $array = array( 2294 => 1, 2292 => 1, 2296 => 1 );
    krsort($array);

    print_r($array)

Output:- 

Array
(
    [2296] => 1
    [2294] => 1
    [2292] => 1
)

Edit:- You can also achieve by set the preserve_keys parameter to TRUE in array_reverse()

   $array = array_reverse($array, TRUE);
   print_r($array);

Try

$array = array( 2294 => 1, 2292 => 1, 2296 => 1 );
$reversed = array_reverse( $array, true );

You need to set the preserve_keys parameter to TRUE:

$result = array_reverse($array, TRUE);
print_r($result);

Output:

Array
(
    [2296] => 1
    [2292] => 1
    [2294] => 1
)

You have to sort on the key: look at this table

You need the ksort() or krsort() functions
