How to get count of shares using face book share button in php?
===

I have a list of events. For each event, I want to add a Facebook share button. An event can be shared only once. The system needs to keep track, how many events an user has shared on FB. I have not used FB share button. I searched but could not find an answer to this. Can we retrieve number of shared events' count for an user ? Suggestions are welcome, how to achieve this, if there is no such API method.
