You can restart PHP-FPM and/or the web server and see if the changes get applied. If not then you definitely did not update the right file or there is another INI file/config taking precedence.
Phpmyadmin is a database tool and has nothing to do with PHP, unironically.
Again, I would recommend looking for guides online specific to your host/server. When in doubt reach out to your server admin and/or hosting provider.
Cheers.
