Download File to server from URL

Well, this one seems quite simple, and it is. All you have to do to download a file to your server is: file_put_contents("Tmpfile.zip", file_get_contents("http://someurl/file.zip")); Only there is one problem. What if you have a large file, like 100mb. Then, you will run out of memory, and not be able to download the file. What I want is a way to write the file to the disk as I am downloading it. That way, I can download bigger files, without running into memory problems.
