How can I retrieve a list of a Wordpress page's sibling pages?

Question

I am trying to create a list of sibling pages (not posts) in WordPress to populate a page\'s sidebar. The code I\'ve written successfully returns a page\'s parent\'s title.

Answer 1

wp_list_pages(array(
    'child_of' => $post->post_parent,
    'exclude' => $post->ID,
    'depth' => 1
));

The correct answer, as both other answers don't exclusively display the siblings.
