Pagination in PDO PHP

im пытается узнать разбиение на страницы с помощью PHP/PDO.Pagination in PDO PHP

  $limit = 20; 
      $sth = $conn->prepare("SELECT * FROM directory WHERE user_active != ''"); 
      $sth->execute(array(':county' => $county)); 

      $c = 1; 
      while ($row = $sth->fetch(PDO::FETCH_ASSOC)) { 
       echo 'Resutls will be here'; 
      $c++; 
      }

Im не зная, что делать дальше, хотя, есть кто-нибудь хорошая отправная точка можно ссылаться из, или может объяснить этот процесс для меня?

Благодаря

'LIMIT' ......... – itachi

Я не вижу никаких проблем с тем, чтобы проголосовать. И кто бы ни проголосовал за это, он должен дать нам повод – Musa

не тестировалось

$page = 1; 
$limit = 20; 
$start = $page * $limit; 

$conn->setAttribute(PDO::ATTR_EMULATE_PREPARES, FALSE); 
$sth = $conn->prepare("SELECT * FROM directory WHERE user_active LIMIT ?,?"); 
$sth->execute(array($start,$limit));

Спасибо @Your Common Sense, как бы я добавил следующие кнопки? – Liam

Итак, нет информации о следующей кнопке или фактических номерах страниц? –

Пожалуйста, используйте код ниже для PAGINATION с помощью PDO:
