It doesn't. At least not on my machine. This is the output I get:
$ php -v
PHP 7.1.0alpha2 (cli) (built: Jun 24 2016 13:50:28) ( NTS )

$ php -a
Interactive shell
php > interface I1 { const C1 = '';}
php > class C3 implements I1 { const C1 = 'c2';}
PHP Fatal error: Cannot inherit previously-inherited or override
constant C1 from interface I1 in php shell code on line 1

string(2) "c2"

So it crashes with a fatal error when Implementing the interface. It'S
interesting though that the script allows me to instantiate the class
nonetheless. That's right.
Perhaps some C-Guru can shed some light here?
Cheers
