API, code to get last post

[ChristianAlfred]

I have this code that works.

PHP Code:

<?
if (isset($_GET['days'])) {
  $num_days = (int)$_GET['days'];
} else {
  $num_days = 10;
}

if (isset($_GET['wanted'])) {
  $channel_id = 17;
} else {
  $channel_id = 17;
}

$channel_id = '17","14","15","16","19","2347499","2359981';

// Path to the vBulletin 5 folder.
// '.' indicates current directory where the .htaccess file resides.
$vbpath = '..';
define('CSRF_PROTECTION', false);
require_once($vbpath . '/includes/vb5/autoloader.php');
vB5_Autoloader::register($vbpath);
vB5_Frontend_Application::init('config.php');

$api = Api_InterfaceAbstract::instance();

$search_json = '{"channel":["'.$channel_id.'"],"starter_only":1,"date":{"from":"'.$num_days.'"},"sort":{"lastcontent":"desc"},"view":"","exclude_type":["vBForum_PrivateMessage"]}';
$search_json = '{ "last":{"from":"7"}, "view":"topic","starter_only":"1", "sort":{"lastcontent":"desc"}, "channel":["17","14","15","16","19","2347499","2359981"] }';


$threads = vB_Api::instanceInternal('search')->getInitialResults($search_json, 30, 1);

$i = 0;
$thread_returns = array();

foreach ($threads['results'] as $tid => $thread_details) {
  $i++;


  $thread_returns['results'][$i] = array(
    'title'         => $thread_details['content']['title'],
    'publishdate'   => $thread_details['content']['publishdate'],
    'channeltitle'  => $thread_details['content']['channeltitle'],
    'userid' => $thread_details['content']['userid'],
    'description' => $thread_details['content']['description'],
    'authorname' => $thread_details['content']['authorname'],
    'uniqueid' => $thread_details['content']['nodeid']


  );
  $thread_returns['results'][$i]['postlink'] = vB5_Route::buildUrl(
    $thread_details['routeid'] . '|fullurl',
    array(
      'nodeid' => $thread_details['nodeid'],
      'title' => $thread_details['title']
    )
  );
}
$thread_returns['totalRecords'] = count($thread_returns['results']);
$thread_returns['searchJSON'] = $search_json;
$thread_returns['days'] = $num_days;

if ($thread_returns['totalRecords'] > 0) {
  header('Content-Type: application/json');
  echo json_encode($thread_returns);
}

?>

It display latest updated posts on my frontpage https://www.zoopet.com

I want to get latest text and latest date from the post. Is there any $thread_details['content']['lastpostdescriptioin'] or something like that.
