Dear BrowserUk,
Thanks a lot for the response. But your code above returns this only:

$VAR1 = {
          'flintstones' => {
                             'fred' => 'barney'
                           },
          'jetsons' => {
                         'george' => 'jane'
                       }
        };

Please correct me if I'm wrong. And also the size of the array may not be even.
