two questions post variables and GD lib.
Posted: Fri Nov 08, 2002 8:26 am
i am trying to understand some things a little better. if you have register_globals off and you are using a form(page1) that posts data to a page(page2) that process that what happens if there are two users in this process at the same time. Are the $_POST variables confined to each instence of the browser?
The second questions is where can i learn how to use the GD library? are the image functions all i need to be come familar with?
Thanks for your help
