user management software -- integration of entire site

[Guest woocha]

Hello everyone, I am a newbie and looking for something that can tie in all of my software together. I want it so that when a user visits my website and logs in to my phpbb forum they are automaticall logged into my classifieds(http://www.geodesicsolutions.com/products/classifieds/classifieds_basic.htm) section as well and also my photohosting software and auctions(http://www.phpauction.net/gpl.php). Whenever someone logs into any of the above or changes there profile in any of the above, I want the login or effected change to occur in all software. Does anyone have any thoughts on this? thank you all for any and all help, sean

That's a fairly big task, and well beyond the scope of a simple explanation of concept. What you're talking about is session management, and you need to make all of the different sessions work together, which means you need to understand the session models for each case, then write something that will transfer them. I'm not sure how much experience exactly you have, but if you're completely new to php, this is a pretty bad intro project; try some simple things like dynamic pages and data accesses first. Work your way through php tutorials (start with the w3cs one, of course), do exmple projects, and learn the ideas of web programming a bit more. While your there, learn the internals of phpBB, especially its session system (which is MySQL based) along with your other systems. Beyond that, if this is mission-critical, I suggest hiring a coder, I'm sure you can find one for a small project like this for fairly cheap.//Matt
