Upgrade PHP to New Version

Question

My CentOS7 server has a very old version of PHP installed (v7.2.10). I am trying to upgrade to PHP8 but am having some major issues. My server has PHP Version Switcher installed and when I try to have it install PHP8, I keep getting an error

I then tried to use yum to install PHP8. It seemed to install fine but php -v still returns 7.2.10. I ran yum list installed | grep php and it returned

Running systemctl status cwp-phpfpm.service returns

So it looks like PHP 7.2 and 8.0 are both installed. How do I have CentOS use PHP8 instead of PHP7.2?

CentOS 7 has reached its end of life in June

Please read: https://blog.centos.org/2023/04/end-dates-are-coming-for-centos-stream-8-and-centos-linux-7/

For your problem, you have multiple versions installed, so read the remi repository FAQ

But you are using cwp-phpfpm so none of the php* or php72* packages are used.
