[PHP-BUG] Bug #77507 [NEW]: No fatal error when implementing interface method with parameter type declared

From:             a dot owrew at gmail dot com
Operating system: Linux
PHP version:      7.2.14
Package:          PHP Language Specification
Bug Type:         Bug
Bug description:No fatal error when implementing interface method with parameter type declared

Description:
------------
As it states in the summary, up until PHP 7.1.26, implementing an
interface method without providing the full signature would cause a
fatal error. Starting PHP 7.2.0 it appears to be more lax. In the
example, the missing string parameter type is causing a fatal error
prior to PHP 7.2.0.

Test script:
---------------
<?php

interface SomeInterface {
    public function setSome(string $some);
}

class SomeClass implements SomeInterface {
    public function setSome($some){}
}

Expected result:
----------------
Fatal error: Declaration of SomeClass::setSome($some) must be compatible
with SomeInterface::setSome(string $some)
