What I'm trying to do is to construct a dynamic image that displays on a map all the zip codes my users have entered. I was hoping to use PHP image functions like imagecreate() to do the trick... I already have a mysql table matching latitude-longitude to zipcodes. The only thing I need to do is to draw the zipcodes from clients I've stored in separate table onto this map. Does anybody have a solution for this, or know of GIS mapping solutions for PHP that would do the trick?
