How to convert an array variable to a single variable.

I have the output of the code below in a count command and need to get the answer into a single variable... like $dog = 88; but so far unsuccessful.. is there a simple way to do it..
I have tried $result[0] and $result[total] when I temp changed the query to as total but nothing seems to work...

(
  [0] => stdClass Object
  (
  [COUNT(*)] => 88
  )

$results = $wpdb->get_results('SELECT COUNT(*) FROM wp_realty_listingsdb WHERE DOM = 0');
print "<pre>";
print "Total DOM 0 = ";
print_r($results);
print "</pre>";

Code (markup):

 

This should work for the as total version: $result[0][total]

 

Thank you for you assistance however that did not work either but i found a solution.

 

Then you should post the solution here, so that others can find it if they're looking for a solution to that problem.

 

Well if anyone is curios since he's using wpdb it has some parameters you can pass to it
One of three pre-defined constants. Defaults to OBJECT.

• OBJECT - result will be output as an object.
• ARRAY_A - result will be output as an associative array.
• ARRAY_N - result will be output as a numerically indexed array.

$results = $wpdb->get_results('SELECT COUNT(*) FROM wp_realty_listingsdb WHERE DOM = 0',ARRAY_N);

Code (php):

Then just $result[0][0] . Hope that helps anyone else with that issue.
