我有以下脚本，需要按字母顺序对内部foreach循环进行排序，但没有成功。

$args = array( 
        \'post_type\' => \'clinical_sites\',
        \'tax_query\' => array( 
                    \'relation\' => \'AND\',
                    array(
                            \'taxonomy\' => \'research\', 
                            \'field\' => \'slug\',
                            \'operator\' => \'AND\',
                            \'hide_empty\' => false,
                            \'terms\' => $researchName
                    ),
                    array( 
                            \'taxonomy\' => \'country\',
                            \'hide_empty\' => false,
                            \'operator\' => \'IN\',
                            \'field\'    => \'term_id\',
                            \'terms\' => $fatherTermId 
                        ),
                    ),
        \'hide_empty\' => true,
        \'posts_per_page\'=>-1,
        \'parent\' => \'1\'
    );
    $query = new WP_Query( $args );
    if ( $query->have_posts() ) {
        while( $query->have_posts() ) { $query->the_post();

            $args3 = array( 
                \'orderby\'  => \'ID\',
                \'order\'    => \'DESC\',
                \'childless\' => true
            );
            $terms = wp_get_object_terms( $post->ID, \'country\', $args3  );
            if ( ! empty( $terms ) && ! is_wp_error( $terms ) ){
                foreach ( $terms as $parent_term ) {


                        ?><option value="<?=$parent_term->name; ?>" data-is-parent="<?=$isparent?>" data-term_id="<?=$parent_term->term_id; ?>" ><?php echo $parent_term->name?></option><?php
                } 
            }
        }
    }
