How to Order a list of taxonomies? orderby?

Question

I am using this code to fetch a list of child taxonomies. I want the order displayed to be alphabetical, but it is not! Any help in figuring out how to do it? I guess ordering it before returning it will be most optimal?

thanks

<?php
$termID = 4;
$taxonomyName = "location";
$termchildren = get_term_children( $termID, $taxonomyName );

echo '<ul>';
foreach ($termchildren as $child) {
$term = get_term_by( 'id', $child, $taxonomyName );
echo '<li><a href="' . get_term_link( $term->name, $taxonomyName ) . '">' .   $term->name . '</a></li>';
}
echo '</ul>';
?>

If you use the more generic get_terms you can include in the $args field all of the information to get the term or the children and specifically say what you want to order by and how you want it to be ordered.

Ex.

$termchildren = get_terms( "location",
                             array(
                                   'child_of' => 4,
                                   'orderby' => 'name',
                                   'order' => 'ASC'
                                  )
                         );

child_of: Get all descendents of this term. Default is 0. Make sure you use an integer value. Like 1, 2, 3, 4 and not '1', '2', '3', '4'.

parent: Get direct children of this term (only terms whose explicit parent is this value). If 0 is passed, only top-level terms are returned. Default is an empty string.
