Sure - but not if f1() takes a reference. It works fine if f1() takes a
value.

For instance, what is supposed to happen if you do something like:

function f1 (&$i) {
$i++;
}

Java and C++ handle this by not allowing a temporary to be passed as a
reference (compiler error) - which is correct operation, IMHO.
