PHP SQL 준비된 문을 사용할 때 코드 반복을 어떻게 피할 수 있습니까?

$data = [$taskName, $startDate, $completedDate];
$sql = 'INSERT INTO tasks VALUES(null, ?, ?, ?)';
$db->prepare($sql)->execute($data);

function prepared_insert($conn, $table, $data) {
    $keys = array_keys($data);
    $keys = array_map('escape_mysql_identifier', $keys);
    $fields = implode(",", $keys);
    $table = escape_mysql_identifier($table);
    $placeholders = str_repeat('?', count($keys) - 1) . '?';
    $sql = "INSERT INTO $table ($fields) VALUES ($placeholders)";
    $conn->prepare($sql)->execute(array_values($data));
}

public function create($data): int
{
    $fields = $this->makeFieldList($data);
    $placeholders = str_repeat('?', count($data) - 1) . '?';

    $sql = "INSERT INTO `$this->table` ($fields) VALUES ($placeholders)";
    $this->sql($sql, array_values($data));

    return $this->db->lastInsertId();
}

class UserGateway extends BasicTableGateway {
    protected $table = 'gw_users';
    protected $fields = ['email', 'password', 'name', 'birthday'];
}

$data = [
    'email' => '[email protected]',
    'password' => 123,
    'name' => 'Fooster',
];

$userGateway = new UserGateway($pdo);

$id = $userGateway->create($data);
echo "Create: $id", PHP_EOL;
