php - 2 Pdo Selects are they working? -

-

so asked on here few months ago own traffic exchange website users earn coins viewing other users websites , gain coins. on surf page grab random user there coins higher 1 grab 1 of there websites use. im wondering if both pdo selects linked ?? grabbing username first select second one?

$stmt9 = $db->prepare('select * users coins >= ? order rand() limit 1'); $stmt9->execute( array('1') ) ; $row = $stmt9->fetch();  $stmt212 = $db->prepare('select    *     websites w w.owner    in (select u.username users u u.coins >= ?)   order    rand()  limit    1'); $stmt212->execute( array($row['username']) ) ; $row212 = $stmt212->fetch();

variables messy know.
