Removing comments from configuration files with sed

Using the below one liner I do what the $subject of the post says:

 sed -e '/^;/d' -e '/^$/d' /etc/php.ini > /tmp/php.ini-stripped

-e '/^;/d'     -- deletes the lines starting with ; and this can be changed to # of course;
-e '/^$/d' /  -- deletes the white lines resulted after the above command;
