Bug description: Confusing error message for empty(func())
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
