PHP – 如何在预处理语句中将数组替换为主机参数

// a helper function to map Sqlite data type
function getArgType($arg) {
    switch (gettype($arg)) {
        case 'double':  return SQLITE3_FLOAT;
        case 'integer': return SQLITE3_INTEGER;
        case 'boolean': return SQLITE3_INTEGER;
        case 'NULL':    return SQLITE3_NULL;
        case 'string':  return SQLITE3_TEXT;
        default:
            throw new InvalidArgumentException('Argument is of invalid type '.gettype($arg));
    }
}

$sql = "SELECT * FROM table_name WHERE id IN (?)";
$params = [[10,9,6]]; // array of array
$dbpath = '/path/to/sqlite.sqlite';
$db = new SQLite3($dbPath,SQLITE3_OPEN_READONLY);
$stmt = $db->prepare($sql);

try {
    foreach ($params as $index => $val) {
        if (is_array($val)) {
            /************* I am stuck here  *************/
            $ok = $stmt->bindParam($index + 1,$val);
            // Using bindValue also didn't worked!
        } else {
            $ok = $stmt->bindValue($index + 1,$val,getArgType($val));
        }

        if (!$ok) {
            throw new Exception("Unable to bind param: $val");
        }
    }
} catch (Exception $ex) {
    // NO exception is thrown from bindValue() or bindParam()
    $reason = "Error in binding statement. " . $ex->getMessage();
    die($reason);
}

$result = $stmt->execute();
$data = [];
while ($row = $result->fetchArray($mode)) {
    $data[] = $row;
}
var_dump($data);

编辑：我已经尝试过替换单身？在param数组中包含所需数量的问号,但只有当我的数组的值小于1000时它才有效！我认为这是PHP中SQLite3中语句编写方式的限制.
