The Daily WTF: Curious Perversions in Information Technology

That's not C++. C++ does not have "null" as a value. It's either NULL (old style) or nullptr. So the code snippet is either C# or Java I guess.

Depending on the language here, this might be valid.

In some languages, false == 0 == null == "" == []

If you want to coerce any "falsy" value to null for sanity, you might do the above.

But then again, I would do it like this:

$foo = $foo?$foo:null;

And probably leave a comment to say as much.
