ID の配列を指定した PHP を使用して複数の MySQL レコードを効率的に更新するにはどうすればよいですか?

$ids = array(2, 4, 6, 8);

$sql = "UPDATE MyTable SET LastUpdated = GETDATE() WHERE id = ?";
$stmt = $mysqli->prepare($sql);

for ($i = 0; $i < count($ids); $i++) {
    $stmt->bind_param("i", $ids[$i]);
    $stmt->execute();
    echo "Updated record ID: $ids[$i]";
}

$stmt->close();

$ids = array(2, 4, 6, 8);

$params = implode(",", array_fill(0, count($ids), "?"));
$sql = "UPDATE MyTable SET LastUpdated = GETDATE() WHERE id IN ($params)";
$stmt = $mysqli->prepare($sql);

$types = str_repeat("i", count($ids));
$args = array_merge(array($types), $ids);
call_user_func_array(array($stmt, 'bind_param'), ref($args));

$stmt->execute();

echo "Updated record IDs: " . implode(",", $ids);
