I am receiving "User info" whenever the User sends a message inside onMessage() callback. I want to use this user info to fetch some details from MySQL DB. However, I am always receiving Class mysqli does not exist error. How can we connect to MySQL?
This line not throwing any error
$db = new MysqliDb(Config::DB_HOST, Config::DB_USER, Config::DB_PASSWORD, Config::DB_NAME);
But this line throwing error:
$numOfUsersInBet = $db->getValue("bet_users_info", "count(*)");

I am trying to connect to MySQL DB using this library https://github.com/ThingEngineer/PHP-MySQLi-Database-Class inside the onMessage function.
