Answer 1

You never execute the query.
$result->execute();
$rows = $result ->fetchAll();
$query->execute();
while($row = $query->fetch(PDO::FETCH_ASSOC)){

Answer 2

Also it's better to use LIMIT in your query. Something like that:
//to get need page
$per_page = 3;
$page = (isset ($_GET['page'])) ? (int) $_GET['page'] : 1 ;
$result = $conn->prepare(
"SELECT * FROM directory
WHERE user_active != ''
LIMIT ".(($page - 1) * $per_page).", ".$per_page
);
$result->execute();
$rows = $result ->fetchAll();
//to get count of pages
$result = $conn->prepare(
"SELECT COUNT(*) FROM directory
WHERE user_active != ''"
);
$result->execute();
$total-pages = reset($result->fetch(PDO::FETCH_NUM));
