Here we can get the field collections item id or entity id using $node with the help of enitity apis -:

<?php
$node = node_load(369); 

$items = field_get_items('node', $node, 'field_contacts');

//here items are having the entity id/itemid

foreach ($items as $item) {

 $fc = field_collection_field_get_entity($item); // Do something. 

}
?>

Note -:

field_get_items() - : It gives all the related entity id and revision id for the field collection . Here our field collection name is "field_contacts";

field_collection_field_get_entity()-: This entity api helps us to get all the relative information for the entity id in all the related tables.
