I don't agree with this. I find this kind of operator a specific 
necessity of PHP. In C you generally know when you have a variable 
assigned and when you don't. In PHP you have lots of situations where 
you have to test whether something has been set or not due to the nature 
of the environment (you don't know what happened in the previous page - 
in C you do know what a window does). That's because, as we all know too 
well, we operate PHP in a stateless environments - therefore you always 
have to check for stuff.

I merely proposed an assignment operator, not a new type of block. The 
funny thing is that you'd gain horizontal space instead of losing it:
if (!$whatever)
  $whatever=something; // defaulting to something

You just wasted a TAB for indentation - whatever the tab size is. Just 
to remind you, if you want to be formatting correct, the recommended TAB 
size is 8 chars. Whereas

$whatever^=something; // defaulting to something

wastes only one character (the caret).

What I have to agree with is that it's not standard. That is correct - 
but I would find this operator useful and I'd be willing to sacrifice a 
bit of "standardness" in favor of writing less.
