Subject: preg_replace(string, null) is allowed?
From: david.proweb@gmail.com (David Rodrigues)

Hello!

I am in doubt if passing null as the second argument to preg_replace() is
valid. Actually, it works as expected.

https://3v4l.org/0TITS

But doc only accepts array|string.

I am asking for it because PhpStorm will not accept it. So if it is valid,
I will do a PR to PS stubs.

Thanks!


Atenciosamente,
David Rodrigues
