I am creating a .env file on UNIX server.
Please recommend me what mandatory things should be added into it.

You don't have to create .env file unless there is a specific need for it. The best contents for this file, in fine Zen tradition, would be no contents and no file.

how we can have a .YAML file for each module
and how we can load this last without loading YAML files from other modules
thank you so much
You cannot load a given config file on demand. Symfony uses compiled container so it's static.

As you know when if a stranger know the path of your SQLite database file he can easy download it. my question is how to avoid that?
I'm assuming you're accessing the SQLite database server-side. You could configure whatever host you're using (apache, nginx, etc...) to not allow access to the file or you could change the permissions to the file to only allow you to view it (using chmod).

Every week I need to download a file from an .aspx site. On the site I select the start and the end date using basic HTML input form, and I would automate this task so to avoid to have to do it manually. Is there a way to do this using wget? I'm open to other solutions
Sure it can be done with wget. Just add --post-data 'startdate=1.1.2016&enddate=1.1.2017' parameter. Change field names startdate and enddate to those on remote web form.
You can also try Selenium Web Driver that is used to automate web site testing.

I just wondered and start reading SQLite source code.
There weren't any fopen,fclose except logging functions.
I tried to track down sqlite3_open, sqlite3_prepare, I came into sqlite3parse and stuck.
There is fopen in
sqlite3MemdebugDump
sqlite3Memsys3Dump
sqlite3Memsys5Dump
sqlite3VdbeTransferError
which are debug functions.
Are they wrote their own disk handler?
(I always stunned how professional applications handle this kind of things.)
Summary: How SQLite handle files without fopen?
SQLite accesses files through its OS interface, which is implemented in the os_*.c files.
