SQLyog Connect to MySQL server using HTTP Tunneling
This option saves your day if your ISP/MySQL provider disallows remote access, either by blocking the MySQL port or by giving access to “localhost” only. The response is slow compared to the direct connection or SSH Tunneling method as the data is XML encoded and HTTP is stateless by nature. However, you can use all the cool features of SQLyog.
To use this method, just upload SQLyogTunnel.php to your webserver. SQLyogTunnel.php is available in the SQLyog installation folder. SQLyogTunnel.php exposes the MySQL API as a set of web-services which is used by SQLyog.
