How to write SFTP get request in one line?

Question

linux

There was such task:
It is necessary to receive a remote file from a remote server, through SFTP, in one line.
To do this, there is an SFTP user, with a password (without it, too, in any way).
You also need to do it using a PHP file, let's say the exec () command - which executes commands as in the command line.
Tried all sorts of stupid options, like:

exec('sftp user:[email protected] get /home/www/x1/test/file.php /home/www/x2/test/file.php');

And

exec('sftp user:[email protected]:/home/www/x1/test/file.php /home/www/x2/test/file.php');

And

exec('sftp [email protected] && password && get /home/www/x1/test/file.php /home/www/x2/test/file.php');

But apparently I'm doing it all wrong.
