I have a quick question regarding PHP's return statement. In C++, we're able to perform the following:

... function body ...
return (foo = bar, biz());

Where the variable bar is assigned to foo before the result of biz() is returned.

Is this possible (or something similar) in PHP? The above statement in PHP results in a parse error. Now, I'm aware that I can simply perform the assignment before the return statement, but this is just a contrived example, and I'm curious as to the feasibility.

Edit: Providing a little more clarification. Here is what I'm basically attempting to do in PHP:

return ($foo = $bar, biz())
    || ($foo = $bar, baz())
    || ($foo = $bar, qux());

foo is a global reference in which biz modifies. If biz returns false, the next segment in the OR statement is tested. Because biz returned false, I need to "reset" the value of foo before executing baz and so on and so forth.

I'm aware that what I'm trying to do here is impure, but I'm just curious is an equivalent (or at least similar thing) is possible in PHP.
