I saw the old Joomlart.com link and thread:
https://www.joomlart.com/forums/topic/common-issue-how-to-enable-gd2-extension-in-php-ini/
Mentioned about some valid extension. I get to recently that there are stuff like php redis extensions, and are way worthy stuff as in-memory caches in that it allows a user to store pieces of data in a much more structured, durable, and robust manner.
Are there any certain list where I can find them in listicle. Thanks!
