New Comment:
But this is not the case: I am not trying to change function's return
value; empty() is not supposed to write anything, it just examines the
variables. So here is the confusion.

The error message is clear enough and is used in all cases when you're
trying to change function's return value, like this:
<?php function foo () { return 1; } foo() = 1; ?>

Description:
------------
When calling empty() with a return value from function, it says:
Can't use method return value in write context
It would be definitely less confusing if it said something like:
empty() accepts only variables as a parameter.
Reproduce code:
---------------
<?php
empty(trim(""));
?>
Expected result:
----------------
Fatal error: empty() accepts only variables as a parameter in ... on
line 2
Actual result:
--------------
Fatal error: Can't use method return value in write context in ... on
line 2
