Answer 1

find /var/www/site.net/blog/ -iname '*.php' -exec grep -l "\$lang\['" {} \; \
-exec sed -i.bak "s/$lang\['\([^']*\)']/$lang['\U\1']/" {} \;

-i option is used with .bak to make backup file with .bak extension on the each file sed will change. It is useful in case there is type in sed and you will not loose all your data. In case you're sure everything is ok, you can use just -i. In this case it won't make a backup.
