So I am trying to make a JSON object that should hold some information

So I am trying to make a JSON object that should hold some information about some questions for me. This is a pseudo-code of how I want it to be presented:

{
 "page" : 1,
 "info" :
          {
           "id" : 1,
           "type" : 3,
           "description": "How to do JSON?",
           "alternatives" : 
                           {
                            "id" : 1,
                            "description" : "Dunno"
                           }
                           {
                            "id" : 2,
                            "description" : "Let me show you"
                           }
                           { 
                            "id" : 3,
                            "description" : "I refuse to show you"
                           }
           }
           "id" : 2,
           "type" : 1,
           "description": "Do you get it?",
           "alternatives" : 
                           {
                            "id" : 1,
                            "description" : "Yes"
                           }
                           {
                            "id" : 2,
                            "description" : "No"
                           }
           }
}

So the code underneath is from Nightmare (one of the answers), and it does exactly what I want to do with the page and the questions, but I can’t seem to figure out how to connect alternatives to each question. You can see a snippet at the bottom where I have tried but it’s not correctly spelled and I’ve been hammering at this for a while now.

$before_json_encode[$row['page']][] = array(
  'id' => $row['id'],
  'type' => $row['type'],
  'description' => $row['description'],
  'alternatives' => $alternativesarray//im not sure about here,dont know the structure of the alternative array
);

Another illustration on how I want the hierarchy of the JSON data to appear. I need to be able to pick for instance: All alternatives to all questions on a specific page. So if I want to generate page 3 in my poll I can first find the questions within the page 3 sub-array, and then again from each question gain access to all of it’s connected alternatives in that questions’s own sub-array. Sorry for the poor explanation of my issue, it’s just a bit complicated :/

Update: 3rd layer:

$rows_test2[$r['page']]
['id' => $r['id'],
'type' => $r['type'],
'description' => $r['description']]
[] =
        array (
        'altid' => $t['altid'],
        'altdesc' => $t['altdesc']);

    $rows[] = array(
    "page" => 1,
    "info" => array(
        "id" => 1,
        "type" => 3,
        "description" => 'desc',
    )
);
echo json_encode($rows); // [{"page":1,"info":{"id":1,"type":3,"description":"desc"}}]

    Update:

    $alternativesarray[]=array('id'=>'1', 'description'=>'yes');
$alternativesarray[]=array('id'=>'2', 'description'=>'no');
$rows[] = array(
    "page" => 1,
    "info" => array(
        "id" => 2,
        "type" => 3,
        "description" => 'desc',
        "alternatives" => $alternativesarray
    )
); 
print json_encode($rows); // [{"page":1,"info":{"id":2,"type":3,"description":"desc","alternatives":[{"id":"1","description":"yes"},{"id":"2","description":"no"}]}}]
