我能够绑定int,str,bool和null类型的值,但我无法绑定数组类型.
我已经尝试了两个函数,即bindValue和bindParam,但它们都没有工作.
我怎么能做到这一点？

// 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 bind@R_547_1403@
    $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.
