[phplib] Registering form variables From: Rex Byrns (rexb <email protected>)
Date: 09/12/00

I would like for someone to explain the use of form variables in sessions.
The manual distinctly points out that you should never trust unvalidated
user input from the internet. I repeatedly see chances to benefit greatly
from registering form variables. A shopping cart uses "form variables" to
track purchases. What exactly is the difference? Are these warnings only
for the scary stuff like user names, passwords, addresses, etc?

Thanks
        Rex
