Hey Internals, Recently i've been working on an older code base, where we have a lot of classes with all static methods. We've been moving to injecting the classes, and calling the methods as if they were not static.
I wanted to add interfaces to these classes, with non static methods, so we can pretend in our implementation they are not static, and allow us to easier switch to non static methods in the future. This is (currently) not allowed by the language: https://3v4l.org/WKdvM Is there any chance of this being possible in future versions of PHP? This would only allow 'normal' methods to become static. Making static methods non static would break Liskov substitution principle in PHP as you may not be able to call the method in the same way. This means you can't have a 'normal' method become static in an inherited class, and then become 'normal' again in another inherited class. This works the same way with co/contra-variance in return/parameter types: (https://3v4l.org/j1SO9) -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: https://www.php.net/unsub.php
