I collect zipcodes on my website and want to display the zipcodes with their appropriate cities and states so I know where my users are coming from. How would I do this? I was thinking about having php parse a text file with zipcode state/zip fields, but I can't find this type of information on the net. Does anybody know where you can download zipcode information or if there is any other easy way to do this?
The table I found actually include latitude and longitude for each zip code. Does anybody know a simple way to overlay this information over a dynamic map with php/mysql? So a map of the US would appear and dynamic points would be generated on the map where users supplied their zip codes?
