in https://www.php.net/manual/en/ref.pdo-mysql.connection.php there is a
note from "divinity76 at gmail dot com" ,
can someone add backslashes to the code? like

<?php

$db = new \PDO('mysql:host=localhost;dbname=testdb;charset=utf8mb4',
'username', 'password', array(
    \PDO::ATTR_EMULATE_PREPARES => false,
    \PDO::ATTR_ERRMODE => \PDO::ERRMODE_EXCEPTION
));
