I am new here, and I am new in programing to and I want to make a dropdown list for my website and I did but in javascript and now I want it to do in php and mysql.

So, here is the point: I have 3 dropdown lists: 1.country 2.region 3.city

I want this list to be populated from database since are a lot of country and region and city... and when I select first item the second to be populated with region from the first country I selected and so on for the third list when i select region in the city list to appear only the city from that region. Is there anybody that knows how to do this or have a script, or a link to a script that can do this. I really apreciate your help.

Kind Regards!
