After doing the tutorial got this error. I am assuming this is related to how I declared the variables.
I have never worked with php, therefore I apologize if this is an easy fix.

Please revert index.php and check README for .env file usage

I am getting a "Fatal error: Uncaught TypeError: Argument 1 passed to Hitrov\OciConfig::__construct() must be of the type string, bool given, called in /www/wwwroot/..."

This could happen when env file wasn’t parsed (not found) - you didn’t rename .env.example to .env, for instance.

Thank you very much for the help. Actually, I did it using cmd in my windows. It worked perfectly. Then I zipped all files and uploaded to my Apache web server and opened the index.php file in browser using domain name.
