  $reponse->execute(array(
    ':login' => $login,
    ':mdp' => $mdp,
    ':email' => $email,
    ':id' => $repo['id']
  ));
} catch (Exception $e) {
  die('Erreur de requete : '.$e->getMessage());
}
$json = json_encode($reponse->fetchAll());
$reponse->closeCursor();
echo $json;

如果表格未使用已发布的查询进行更新，请尝试检查更新查询id value中的WHERE clause。

// Check if any data is found
$check = $db->prepare('SELECT COUNT(id) FROM utilisateur WHERE id= :id');

$check->execute(array(
    'id' => $repo['id']
));

var_dump( $check->fetchColumn() );

如果没有结果返回，那么您知道$ repo [＆＃39; id＆＃39;]不在桌面上。
