How does Laravel read the .env file?
I have already looked at the repositories of Illuminate (from Laravel) and found nothing that would give me a hint as to how to read this file.
Is there a library, which Laravel uses, that does this? And if so, what is the name?
You have a library called vlucas/phpdotenv that has this responsibility in reading the file .env .
No% of Laravel has this package configuration.

},
In Laravel in specific its use would be done loading the file in composer.json in the method just below:
/**
* Register a callback to run after loading the environment.
*
* @param \Closure $callback
* @return void
*/
public function afterLoadingEnvironment(Closure $callback)
{
return $this->afterBootstrapping(
'Illuminate\Foundation\Bootstrap\DetectEnvironment', $callback
);
}
has other related methods too, but this being the primary one.
