So I've installed the REMI PHP on RHEL 7. It is PHP 7.2 Also included is the Oracle Instant Client. I've set the correct LD_LIBRARY_PATH.
When I run php -m it shows the module. oci8. When see if the module is installed via php Code is says YES via command line and NO via the NGINX/PHP_FPM.
The PDO even says that OCI is a driver on the PHP command line side and not via PHP-FPM on the web.
Not sure what I could be missing.
