Enable remote access to MySQL database server on wampserver

Just use mysql 'GRANT' command for the database user to connect from 'any host', not from 'localhost', like that,
 mysql> GRANT ALL PRIVILEGES ON *.* TO myUser@localhost
IDENTIFIED BY 'pass';
mysql> GRANT ALL PRIVILEGES ON *.* TO myUser@"%"
IDENTIFIED BY 'some_pass';

"%" - is a wildcard in mysql. If you are defining your DB table and in the 'host' field enter '%', that means that any host can access that database (Of course, that host must also have a valid db user).
