I have an array like this (output from print_r):

Array
(
    [price] => 700.00
    [room_prices] => Array
        (
            [0] => 
            [1] => 
            [2] => 
            [3] => 
            [4] => 
        )

    [bills] => Array
        (
            [0] => Gas
        )
)

I'm running a custom function to convert it to an object. Only the top-level should be converted, the sub-arrays should stay as arrays. The output comes out like this:

stdClass Object
(
    [price] => 700.00
    [room_prices] => Array
        (
            [0] => Array
        )

    [bills] => Array
        (
            [0] => Array
        )
)

Here is my conversion function. All it does is set the value of each array member to an object:

function array_to_object( $arr )
{
    $obj = new stdClass;
    if ( count($arr) == 0 )
        return $obj;

    foreach ( $arr as $k=>$v )
        $obj->$k = $v;

    return $obj;
}

I can't figure this out for the life of me!
