[PHP-BUG] Bug #74289 [NEW]: Strange behavior when casting the types of functions/methods

From:             erickskrauch at yandex dot ru
Operating system: Linux
PHP version:      7.1.3
Package:          Scripting Engine problem
Bug Type:         Bug
Bug description:Strange behavior when casting the types of functions/methods

Description:
------------
I'm not sure if this is a bug, but when I was developing a wrapper for
xml document, I ran into strange behavior when casting types in the
return value of the method. I expect that the asInt() method will work
just like the directConversion(), but they work differently.

Test script:
---------------
https://3v4l.org/JnFCh

Expected result:
----------------
string(3) "123"
int(123)
int(123)
int(123)

Actual result:
--------------
string(3) "123"
int(123)
int(123)

Fatal error: Uncaught TypeError: Return value of Parser::asInt() must be
of the type integer, object returned in /in/JnFCh:22
Stack trace:
#0 /in/JnFCh(44): Parser->asInt()
#1 {main}
  thrown in /in/JnFCh on line 22
