Replace multiple new lines only

I am trying to do something kind of unusual. I want to replace multiple new lines with two new lines. There are plenty of questions like that but not exactly, see:

Hello\n\n\nWorld\n\n\n\n!

Should become

Hello\n\nWorld\n\n!

This however

Hello\nWorld\n!

Should stay the same. The problem with my regex is that it replaces single new lines with two.

preg_replace('"(\r?\n)+"', "\n\n", $somevar)
