Thank you, Dismounted. The subdomains are all on the same server. Yes I changed the path internally and this method works. But I still have these questions:
1. Will this method (chdir, etc.) affect my own script that is on the other subdomain? Will it be heavier? Will it produce any errors? Are there any functions that I should not run in the script?
2. What are the variables that I can retrieve and how? For example, I need to retrieve:
UserID
Username
Email
Member Level (regular, admin, etc.)
Thank you.
Never mind. Got that
