Using a function that can recursively go through your JSON, you can get the functionality you wish. Consider the following code: (this only accounts for an attribute of id as getting listed, as your desired code shows)

$json = '[{"id":3,"children":[{"id":4,"children":[{"id":5}]}]},{"id":6},{"id":2},{"id":4}]';

function createOLList($group) {
    $output = (is_array($group)) ? "
" : "";
    foreach($group as $attr => $item) {
        if(is_array($item) || is_object($item)) {
            $output .= createOLList($item);
        } else {
            if($attr == "id") {
                $output .= "
$item
";
            }
        }
    }
    $output .= (is_array($group)) ? "
" : "";
    return $output;
}

print(createOLList(json_decode($json)));

This will produce the following HTML output.
