Hi, I would like to include a version checker/update utility with a php program I am writting. Can someone tell me what php commands would be needed to write a script that would compare the versions or dates of a customers php files against those from a remote server and provide a way for the customer to upgrade the php files either individually or as a whole over the web? Thanks!
