function return values

[sinister]

If I assign a variable to a function, say,
$x = f($y);
and then f happens not to return anything, does $x just remain unset? Or is
this illegal?

Of course, that should read <admission ...>

One reason I wanted to ask, not just test, is that I couldn't find the
answer in documentation, and there's always the danger that one
instantiation of the language will do it one way, and another another way.

No. $x would return NULL

Couldn't f() return NULL when it does not specifically returns something else?
