Unable to get remote file name file_get_contents () and then save file

I want to download a remote file and put it in my server directory with the same name as the original. I tried to use file_get_contents($url).

The problem is that the file name is not included in $urlit as www.domain.com?download=1726. This url gives me for example: myfile.exeso I want to use file_put_contents('mydir/myfile.exe');.

How can I get the file name? I tried get_headers()before downloading, but I only have the file size, date of modification and other information, the file name is missing.
