[PHP-BUG] Bug #74315 [NEW]: Fatal error: Declaration of test2::test() must be compatible with test1::test()

From:             spam2 at rhsoft dot net
Operating system: Linux
PHP version:      7.1.3
Package:          Scripting Engine problem
Bug Type:         Bug
Bug description:Fatal error: Declaration of test2::test() must be compatible with test1::test()

Description:
------------
it's annoying enough at all that you get warnings when method
declarations are not 100% identical in case of adding param-type-hints
in the underlying classes without change all extended classes at the
same time but in case of return types a fatal error is just
unacceptable

(and no it also don't make sense that you can't skip optional params in
a extended class or add additional ones to change the behavior of the
parent-call)
________________________________

unacceptable because you can't add them at all without hard breaking
every dervied code while in case of the annoying warnings you can at
least adopt the changes while watching errorlog and sites ar enot
completly broken

[harry@srv-rhsoft:/downloads]$ php test.php
Fatal error: Declaration of test2::test() must be compatible with
test1::test(): array in /mnt/data/downloads/test.php on line 2



Test script:
---------------
[harry@srv-rhsoft:/downloads]$ cat test.php
<?php
class test2 extends test1
{
 public function test()
 {

 }
}

class test1
{
 public function test(): array
 {

 }
}
?>

Expected result:
----------------
no error and in the best case even no warning at all, extedning a class
and override methods in doubt always imply changed behavior with or
without changing method signatures

Actual result:
--------------
Fatal error: Declaration of test2::test() must be compatible with
test1::test(): array in /mnt/data/downloads/test.php on line 2
