Groups vs Woo code (doesn't work)

<?php $user_id = get_current_user_id();

$groups_user = new Groups_User( $user_id );
$groups = $groups_user->groups;
$my_groups = array();

foreach($groups as $g) {
	
	$my_groups[] = $g->name;
	
}

$my_groups = implode(', ', $my_groups);

// And then you can access the groups that the user belongs to using

echo '<p>All applicable customer groups: '.$my_groups.'</p>';

?>
