Morning Internals,
I'd like to announce a RFC to allow omitting the type declarations for
parameters in subclasses:
https://wiki.php.net/rfc/parameter-no-type-variance
PHP doesn't currently allow variance for parameters as checking these for
compatibility isn't possible on compile time.

What happens if the method signature is defined within an interface? I
would consider that method signature a contract and one that should not
be able to be overwritten.

Just the same as for every class. Having other rules for interfaces doesn't
make sense.
Imagine the following example:
interface I { function foo(array $foo); }
class C1 implements

But this leads to code that can't pass static inspections?
interface Joiner {
public function join(array $array): string;
}
class WideJoiner implements Joiner {
public function join($iterable): string {
$array = is_array($iterable) ? $array :
iterable_to_array($iterable);
