I guess I don't understand how a global variable can "step on" a session variable if the only thing I'm assigning anywhere in my application to said session variable is a value from a database query. When PHP changes pages, it might be arbitrarily assigning some value to a session variable, even though I'm not telling it to? > > Can you please explain this to me? Thanks - > It's been a while since I've dealt with either, but I believe the most common way would involve register_globals (and session auto_start?). The session would automatically register global variables named $SSN or $CostCenter in your page that would be tied to $_SESSION['SSN'] and $_SESSION['CostCenter'], even before a line of code was executed. If you then change the value of $SSN - even if you intentionally initialize it to an empty value at the beginning of a script -- PHP would alter the value of SSN in the session itself. I don't know exactly what is happening in your case. All I am suggesting is that if you are getting the correct values from the database and you can see that they have been correctly assigned to the $_SESSION array when you echo them later in the script, the issue is somewhere other than with the database and you need to dig somewhere else for the solution.
