Description:
------------
If array "$pdo_parameters" contains only 1 element then everything works as expected and I receive a result. However when "$pdo_parameters" contains more than one I don't receive any results at all without any exception message. PHP errors are active, but I don't see any PDO error message.

Passing more PDO parameters than needed should result in a PDO error.

Test script:
---------------
// db credentials
$dbhost = "localhost"; $dbuser = "user"; $dbpass = "password"; $dbname = "database";

// pdo
$dsn = "mysql:host=".$dbhost.";dbname=".$dbname.";charset=utf8";
$options = [
  PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
  PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC,
  PDO::ATTR_EMULATE_PREPARES => false
];
$pdo = new PDO($dsn, $dbuser, $dbpass, $options);

$sql = "SELECT * FROM foo WHERE bar > ?";
$pdo_parameters = [ 1, 2, 3 ];
$stmt = $pdo->prepare( $sql );

// PDO exception should be thrown here
$stmt->execute( [ 1, 2, 3 ] );


Expected result:
----------------
Fatal error: Uncaught PDOException: SQLSTATE[HY093]: Invalid parameter number in /tmp/test:18 Stack trace: #0 /tmp/test.php(18): PDOStatement->execute(Array) #1 {main} thrown in /tmp/test.php on line 18

Actual result:
--------------
no error
