Adding a user to a group is permanent.  Messing with permissions on /dev
files often aren't (when udev is involved as it usually is these days).

apache would have to be restarted after changing the group settings.

Debian uses www-data as user for apache.  Other distributions use other
names for it.

ps auxww|grep apache, should show what user and group it runs as.
