PHP access array item by key value

I have a php array ($menu) with child items. I would like to loop inside the items that have the same parent ID, for instance [post_parent] => 36

foreach($menu as $m) {

*where post_parent => 36 ???*
echo $m->title;

}

here is my array :

    [0] => WP_Post Object

You should use foreach and find post_parent equal 36 with if condition like below

foreach($menu as $m) {

    if (isset($m->post_parent) && $m->post_parent == 36) {
        echo "post_parent  36";
    }
}
