i was trying to see the list of child pages name with some description to display ..i use below code

$my_wp_query = new WP_Query();
$all_wp_pages = $my_wp_query->query(array('post_type' => 'page'));
// Get the page as an Object
$portfolio =  get_page_by_title('service');
// Filter through all pages and find Portfolio's children
$portfolio_children = get_page_children( $portfolio->ID, $all_wp_pages );
// echo what we get back from WP to the browser
echo "<pre>";print_r(
);

foreach($portfolio_children as $pagedet):

        echo $pagedet['post_title'];


 endforeach;

i am getting array before using foreach 

when i print  $portfolio_children iam getting out put like this 
 Array
