How to find the Array function when using Rets

I have an array problem and have been working on this for months.

$results = $wpdb->get_results('SELECT COUNT(*) AS $total FROM 
wp_realty_listingsdb');
print "<pre>";
print_r($results);
print "</pre>";

Array
(
    [0] => stdClass Object
        (
            [$total] => 25
        )
)

$results = $wpdb->get_results('SELECT COUNT(*) FROM 
wp_realty_listingsdb');
print "<pre>";
print_r($results);
print "</pre>";

Array
(
    [0] => stdClass Object
        (
            [COUNT(*)] => 25
        )
)

$cars=array("Volvo");

print "<pre>";
print_r($cars);
print "</pre>";

echo $cars[0];

Array
(
    [0] => Volvo
)

Volvo

So as it goes I have no problem using the echo to get the cars variable but no matter what I do I cannot get the variables from the above arrays... I have tried all of the following to no avail.

echo $results['total']
echo $results['0']
echo [0][total]
echo array[0][total]
echo $results['count']

You can see the image of the arrays here as to how they look:

Example #1: (first one using count(*) AS $total)
Example #2: (second one using count(*))
Example #3: (third one and no problem volvo)

Really appreciate any help what so ever.

Solution

You can access the 1st one like the following way

$results[0]->{'$total'}

Same for the second one

$results[0]->{'COUNT(*)'}
