Unfortunately the combination of PHP, doing something which needs root, and
security are inherently contradictory.

The least risky approach would be to invoke the needed command via sudo, or 
possibly a small setuid-root C wrapper program which launches only the needed script
with root permissions.  Use sudo unless your C wrapper is careful enough to use
exec() and not system(), sanitizes $PATH and other env variables, and guards against
games with $IFS, shell metachars, and such.
