That's my question. 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 ) Copyright (c) 1997-2016 The PHP Group Zend Engine v3.1.0-dev, Copyright (c) 1998-2016 Zend Technologies $ 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 Fatal error: Cannot inherit previously-inherited or override constant C1 from interface I1 in php shell code on line 1 php > $c3 = new C3; php > var_dump($c3::C1); string(2) "c2" php > 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?
