My client's websites were moved last year from an old php server to a newer one. At that time, I had to upgrade all her scripts because set_globals were off on the new server, and so I went to using $_SESSION variables. All seemed to be doing fine until sometime last week when the scripts on a new website I am working on, being hosted on her server, started flaking out. Variables were becoming persistent, retaining previous values and refusing to change.
I checked the php settings and found that the version running on the sever is 4.1.2 with globals on. That surprised me. I don't have admin access and would be cautious about trying to change this and possibly messing up someone else's site.
Anyway, to test my theory, I created a simple script that turns session_start on and off. If session_start is off, variables work fine. With session_start on, variable will change once, and then refuse to change. I've attached the script.
Does this indeed mean that I have to go through all my scripts and comment out session_start and convert my $_SESSION defines back?? Yeachh!!
