Description:
------------
According to https://www.php.net/manual/en/function.fpassthru.php fpassthru can return `false`, even though definition is "fpassthru ( resource $stream ) : int". So, there is a contradiction and it seems like in description, rather in definition. Unless it's planned to replace Fatal Error with `false` return.

Expected result:
----------------
Correct description of return values is expected

Actual result:
--------------
Promises `false` in case of error.
