An in-depth understanding of Laravel .. How is the framework set up with configurations?

Question

Laravel

The Laravel documentation unfortunately does not go deep into the understanding of the processes themselves that occur and how exactly the configuration is configured and information is read from the configurations, who can share information about this?
Let's say the database.php configuration how does the framework read settings from the array?
Does anyone have a link to the information that goes exactly through the logical processes of the framework itself?

Answer 1

You can read the source. You should start with app/http/Kernel.php (or better with public/index.php).
Netbeans/phpstorm can help a lot in reading source codes with their ctrl+click on the class name to go to the file with its definition.
