Hello,

I have to create a site with PHP and I need some information (eg.:username, id, mode,...) on all pages. I know some sollutions but I don't know which is the right(secure and fast) way.
I heard some security problems with global variables.
I wondering if I use a global class(object) for these informations is it secure or is it easy to hack the class data and get a full controll on my site?
Is it better to use SESSION variables?

Thanks!

Global vars are in general much more secure than those unregistered ones. As long as you don't store your raw password in a session and make enough checks, you should be on the safe side with SESSION vars.

If you don't know enough about login and data checks, I'd recommend you to check out PHPSecurePages (http://www.phpsecurepages.com), it should show you how to handle that stuff.
