Chained Select boxes using PHP?

[c.mclean]

Hi,

Is it possible to have chained select boxes using PHP? If all the values in the boxes come from a database?

For example:
The user selects a Region (England) - and all the counties in England are populated in the next box
then they select a County (Surrey) - and all the cities in Surrey are populated in the next box
then lastly the user selects a City (Croydon) - and then the user is able to click "Search"

Is this possible using PHP - or another language (except Java/JavaScript)?

Thank you

Unfortunately, to do this AJAX, essentially Javascript, is required.
