$pageMin = (($page * 10)-10);

$reponse = $bdd->prepare('SELECT pseudo, message FROM minichat ORDER BY id DESC LIMIT ?, 10');
$reponse->execute(array($pageMin));

似乎占位符不适用于LIMIT …

当我将pageMin连接起来时，例如：

$reponse = $bdd->query('SELECT pseudo, message FROM minichat ORDER BY id DESC LIMIT' . $pageMin . ', 10');

甚至

$reponse = $bdd->prepare('SELECT pseudo, message FROM minichat ORDER BY id DESC LIMIT' . $pageMin . ', 10');
$reponse->execute(array());

使用占位符，它不会返回任何结果，为什么？

谢谢你的帮忙。
