I have the following error -

Fatal error: Uncaught PDOException: could not find driver

When trying to connect via PDO.

<?php


$host = '127.0.0.1';
$db   = 'mytodo';
$user = 'root';
$pass = 'root';
$charset = 'utf8mb4';

$options = [
    \PDO::ATTR_ERRMODE            => \PDO::ERRMODE_EXCEPTION,
    \PDO::ATTR_DEFAULT_FETCH_MODE => \PDO::FETCH_ASSOC,
    \PDO::ATTR_EMULATE_PREPARES   => false,
];

$dsn = "mysql:host=$host;dbname=$db;charset=$charset";
try {
     $pdo = new \PDO($dsn, $user, $pass, $options);
} catch (\PDOException $e) {
     throw new \PDOException($e->getMessage(), (int)$e->getCode());
}

require ('index.view.php');

I've experienced numerous instances of the same problem, all solved by uncommenting "extension=php_pdo_mysql.dll" in php.ini, but it made no difference to me.

I'm using Windows 10, MAMP and PHP 8.0.1

phpinfo() shows no driver under PDO

Although there is no comment in php.ini

Any help would be greatly appreciated
