Find the Children of a Page then Echo it as a Bulleted List of Links (menu)

Question

I am trying to check if a parent Page has children. If it has children I would like to echo the children as a bulleted list with links to each child (basically a menu).

Right now I have the following code in loop-page.php and it checks if the Page has any children and returns an array with the children. I use an if statement to check if the number is greater than 0.

$children = get_pages('child_of='.$post->ID.'&parent='.$post->ID);

if (count($children)) {
    // Echo children as a bulleted list of links
}

This part seems to work.

My question is how do I echo through the children as a bulleted list of links? Like the example below.

Let's say "Services" is the parent page and its children pages are "Grass Cutting", "Water Gardens", and "Landscaping".

count($children) would return 3 for the "Services" page since it has 3 children. Now it should echo them as so:

<ul>
<li><a href="#">Grass Cutting</a></li>
<li><a href="#">Water Gardens</a></li>
<li><a href="#">Landscaping</a></li>
</ul>

a href= should be the link to the page.

Well you just need to run a foreach loop over your $children but WordPress has a build in function for this already called wp list pages.

For example:

$children = wp_list_pages('title_li=&child_of='.$post->ID.'&echo=1');

if ($children)
echo '<ul>' . $children . '</ul>';
