The output when I entered localhost/[folder_project_name]

For information, this folder I’ve got is the source code for my project. This source code given to me from the lead. I want to make similar laravel project from this old project that using old Codeigniter version 3.

And the previous database using mysql, now I want to take a peek by running this project through localhost for having full experience. And I’ve also set the config.php for connecting to the existing database I’ve imported to the localhost as well.

Cause I never held an Codeigniter projects before and only using Laravel as PHP Framework, I don’t know what to do. I beg your kindness to answer my simple question.
