Interesting, indeed. In C++, for an example, it must work as you
expected, and works indeed, since "something" is first assigned to
$frob, then it's passed over to the function, and it does whatever it
wants with it. Here, however, some double assignments seem to have
happened. Is it a bug, or is it some kind of php-specific behaviour,
other users might now.
