PHP 7.4 Support Period

[horn.kimheang]

Excuse me, Sir. I am really sorry for your inconvenience. I know this 
question may not necessary but I really want to know.

How long does php 7.4.3 (php-fpm) default version of Ubuntu 20.04 support?
The official version just support until 28 November 2022. How about 
Ubuntu php?

I hope you will answer my question.
Thank you so much.
