Saving Dynamically Generated Pages

I’m using PHP to allow a user to update several MySql records in a batch process. During the update I print to the browser information about the update (records deleted, added, changed…etc.). What I would like to do is also save this report so the user can access it at a later time. I’m considering writing all the update information to a datafile before displaying it to the user, say through an include(); What I would like to do is direct the output (all my prints) to that report file. It seems though that I might have to go through my code and explicitly use fputs to accomplish this task. Any suggestions welcome. Thanks, Chris
