});

мне нужно прочитать данные с URL
не статические данные
у меня есть выход массива php json нужно использовать

        $data[] = array(
'latitude' => $value['latitude'],
'longitude' => $value['longitude'],
'group'     => $value['post_category'],
'icon'      => 'http://localhost/zoom/style/default/images/marker-airport.png',
'html' => array('content'=>$value['post_title']),
);

echo json_encode($data);

не данные в маркерах: []
