Use a class instead of an array:

var_dump(json_encode(new StdClass()));

Try This

  $cc['CC'] = new stdClass ;
  echo json_encode($jsonrows['paymentmethods']=$cc);

Output is

{"CC":{}}

For code readability, I use $emptyObject = (object)[];

In the context of your example:

$jsonrows['paymentmethods']['CC']=array(); echo json_encode($jsonrows['paymentmethods']);

yields the undesired: {"CC":[]}

$jsonrows['paymentmethods']['CC']=(object)array(); echo json_encode($jsonrows['paymentmethods']);

gives what you want: {"CC":{}}
