Core Warning: Module 'mongodb' already loaded

Question

Our apps are set up with Laravel and MongoDB, but we're getting a lot of errors relating to Core Warning: Module 'mongodb' already loaded being logged in Sentry.io .

Here are the results from grep -rnw '/etc/php/' -e 'mongodb.so'

/etc/php/7.2/cli/php.ini:1928:extension=mongodb.so
/etc/php/7.2/mods-available/mongodb.ini:1:extension=mongodb.so
/etc/php/7.2/fpm/php.ini:1928:extension=mongodb.so
/etc/php/7.1/mods-available/mongodb.ini:1:extension=mongodb.so
/etc/php/7.3/mods-available/mongodb.ini:1:extension=mongodb.so
/etc/php/7.0/mods-available/mongodb.ini:1:extension=mongodb.so
/etc/php/5.6/mods-available/mongodb.ini:1:extension=mongodb.so

And here are the results from a generic php --ini (notice the error doesn't appear here.)

PHP 7.2.15-1+ubuntu18.04.1+deb.sury.org+1 (cli) (built: Feb  8 2019 15:38:01) ( NTS )

with Zend OPcache v7.2.15-1+ubuntu18.04.1+deb.sury.org+1, Copyright (c) 1999-2018, by Zend Technologies

Do I need to remove one of the ini files above? If so, which one? I'd previously removed duplicate lines of extension=mongodb.so from cli/php.ini and from fpm/php.ini , but the error continues to show up in our Sentry.io event logs.

If php is being run as a web server module, you need to restart the web server itself after you modify php.ini. The configuration will not be loaded automatically if you don't do that.
