This isnt web based but i use mysql workbench. Great tool. Has lots of little time saving features like table templates (can quickly right click and add a new table based upon a template u have created. Real time saver) and many many other goodies.

I'll second MySQL Workbench. For me the other big win over PhpMyAdmin is the security. With PhpMyAdmin, you have to install it on the server you're managing. Which exposes your app to all the security bugs that PhpMyAdmin could possibly introduce. What I love about MySQL Workbench is that it takes a completely different approach; you actually ssh into your server to manage it. It's just a GUI on top of the mysql command line. I'm not saying that PhpMyAdmin is inherently insecure, just that if a bug does exist, you've just exposed your production server to said bug.
