Реализовать ЧПУ с помощью PHP

Помогите реализовать ЧПУ ссылки, на данный момент ссылка на альбом(подробнее) имеет вид: site.ru/single.php?id=1. А нужно site.ru/albums/1 но при этом если ввести site.ru/albums то выводит весь список альбомов, возможно это будет не совсем просто, но буду благодарен за помощь.

Конфиг:

<?
$host     = 'localhost';
$user     = 'root';
$password = '';
$database = 'db';
$connection = mysqli_connect($host, $user, $password, $database);
if (mysqli_connect_errno()) {
    printf(mysqli_connect_error());
    exit();
}
$db = new PDO("mysql:host=$host; dbname=$database", $user, $password);
function get_albums_all()
{
    global $db;
    $albums = $db->query("SELECT * FROM albums");
    return $albums;
}
function get_tracks_all_by_id($id)
{
    global $db;
    $tracks = $db->query("SELECT * FROM tracks WHERE album_id = $id");
    return $tracks;
}
function get_album_by_id($id)
{
    global $db;
    $albums = $db->query("SELECT * FROM albums WHERE id = $id");
    foreach ($albums as $album) {
        return $album;
    }
}
function get_album_by_prev($id)
{
    global $db;
    $albums = $db->query("SELECT * FROM albums WHERE id < $id ORDER BY id DESC LIMIT 1");
    foreach ($albums as $album) {
        return $album;
    }
}
function get_album_by_next($id)
{
    global $db;
    $albums = $db->query("SELECT * FROM albums WHERE id > $id ORDER BY id LIMIT 1");
    foreach ($albums as $album) {
        return $album;
    }
}
