How to get list of Pages?

S0 i’m trying to make a control panel for a theme i’m designing,
And I want to have a setting that lets the user specify a specific page by drop down menu, for a link in on the page.

It works fine for categories:

$LS3_categories_obj = get_categories(‘hide_empty=0’);
$LS3_categories = array();
foreach ($LS3_categories_obj as $LS3_cat) {
$LS3_categories[$LS3_cat->cat_ID] = $LS3_cat->cat_name;
}

How do I make a separate one that can do pages, or better yet both??
