How to set the Date format

[johnwswar]

I'm a newbie to Laravel and Laravel-OCI8 and want to know the best way to set the date format for the entire website. In my controller, I used DB::SetDateFormat('MM/DD/YYYY') to set the date format and was able to insert , update and display date fields with the format (but not sure whether this is the best approach). For some unknown reason, the dateformat is now set to YYYY-MM-DD HH24:MI:SS and the insert and update fails. Previously, I was using Laravel 7 and now has upgraded to Laravel 8. Thanks.
