I need to develop an interactive map (Show map and point with some related data) with OpenLayers from client side but from server side I don't know what I should use. GeoServer seems to be much more than what I need.
What I need is a service that accepts and it responds with WFS. Considering that I have access to the database that stores the transactional and georeferenced data.
Can I develop my own implementation of web service in PHP? Are there existing libraries? If not, what do you suggest?
