Upgraded php to 7.4 but Libre still is using php 7.2

[dct723]

Upgraded php to 7.4 when I do ./validate.php the results still show as PHP version 7.2.34. I’m I missing another step? How do I use the newest php 7.4 version.

bash-4.2$ ./validate.php

Its up to your operating system to pick what default php version too use, consult its documentation regarding switching default versions.
You could always uninstall the php 7.2 package

Are you using Apache? If so have you told Apache you have a new PHP to use?

sudo a2dismod php7.2
sudo a2enmod php7.4
