Execute mysqli commands from php nginx

Docker Engine Compose
1

Hi I’m new to Docker & Compose. I’ve created a Docker.yml file with nginx, fpm & mysql. I can execute php commands but I can’t execute mysqli commands. phpinfo.php shows '–enable-mysqlnd’ and it appears to be installed. Configuration File (php.ini) Path /usr/local/etc/php is doesn’t have any php.ini… i’m not sure what to do to get this mysql commands to work. Appreciate some help!
