Hi
In my php page , there is a user registration form. Here the user has to select
the country, state, city from the drop down box. How this can be handled in php?
If a country is selected in a drop down box , its corresponding states should be
populated in the state drop down box. If a state is selected , its corresponding
cities should be populated in the city drop down box. Where all these data has to be stored and retrieved. What type of data storage and datastructure can be used. ? How this can be done in php + javascript ?
