AWS MYSQL RDS connection over SSL

Using Doctrine and in 'driver' => 'pdo_mysql'.

I am trying to connect with the AWS MYSQL instance over SSL, but getting failing.

As per MySQL and AWS Document i have to provide --ssl-mode=required.

I have tried this: but it looks like pdo_mysql doesn’t support sslmode option.

       $options = [
            'dbname' => $dbName,
            'user' => $user,
            'password' => $password,
            'host' => $host,
            'driver' => 'pdo_mysql',
            'sslmode' => 'REQUIRED',
        ];
        return DriverManager::getConnection($options);

And even with PHP PDO also:

        $pemPath = __DIR__ . '/global-bundle.pem';
        $pdoOptions = [
            PDO::MYSQL_ATTR_SSL_CA => file_get_contents($pemPath),
            PDO::MYSQL_ATTR_SSL_VERIFY_SERVER_CERT => false,
        ];
        $pdo = new PDO("mysql:host=$host;port=3306;dbname=$dbName", $user, $password, $pdoOptions);
        return DriverManager::getConnection(['pdo'=>$pdo]);

But getting no success.

The only way I got success when I connect using the command line:

mysql -uUser -p -h mysql-xx-abc.eu-west-1.rds.amazonaws.com --ssl-mode=REQUIRED

my php version is 74
