Is there a down side to registering a var with the session more than
once? I.e. which would be preferred and why in a frequently accessed
page in a web application:
session_register('var');
or
If (!session_is_registered('var') session_register('var');
FWIW - either way seems to work without any apparent issues. Seems the
first way avoids a seemingly unnecessary conditional operation.
Thanks...
