I am running this DB call to get me multi-dimensional array I am trying to get the keys of each but when I try it comes up blank or as array. 

$root_array = array();
$sites = $this->sites($member_id);
foreach ($sites as $site){
    $records = $this->db->select('p.name as place_name, p.id as place_id,p.active as place_status')
                ->from('places p')
                ->join('members_permissions pm','pm.sites_id = p.sites_id and pm.members_id ='.$member_id)
                ->where('p.active', 0)
                ->get();

    $places = $records->result_array();
    $places['name'] = $site['name'];
    foreach($places as $place){
       $root_array[$site['name']][] = $place;
    }

}
return $root_array;

here is my php that loops through:

<?php foreach($places as $site): ?>
    <h5><?=key($site)?></h5>
        <?php foreach($site as $place): ?>
            <h6><?=$place['place_name']?></h6>
        <?php endforeach?>

<?php endforeach ?>

Also when I run a test which just spits out the array this is the result, What I am trying to render is [Philadelphia]

[Philadelphia] => Array
        (
            [0] => Array
                (
                    [place_name] => XYX
                    [place_id] => 103200
                    [place_status] => 0
                )

            [1] => Array
                (
                [place_name] => YYYY
                [place_id] => 232323
                [place_status] => 0
            )

You can access your array keys like so:

foreach ($array as $key => $value)
