You can call functions like that without problems UNLESS the function
is expecting values by reference, i.e. results are passed back
through the parameters. If you supply a function result, then you may
as well not be calling the function as you'll never be able to get a
result back from it, hence the error message. e.g.
function foo(&$a, $b) {
$a = $a.$b;
}
If you call this as you asked, where would the result go?

As was suggested, put your values in variables before calling the
function, though the code example you posted suggests you're trying
to do something odd.
