First of all you may need a number of different tables for the different data types, such as two different tables for regions and places.
Secondly what experience do you have in PHP? Not exactly sure what your intention is with the PHP code, but not only does it not really check out syntax wise, (you need to use a period instead of comma for concatenate) your html will also appear with a </select> tag after every option, meaning no drop down will appear.
Basically, please outline what experience you have, what you are trying to do, and the specific code which is not working. If you are trying to create a very complex application with very limited experience you may want to try something more simple to start off.
