It would hit a lot of existing code for what is really mostly a cosmetic difference. Besides, PHP doesn't need to warn of this specific issue, code sniffers and IDEs can do that if they want. ------------------------------------------------------------------------ [2016-07-15 20:07:56] nikic@php.net @dmitry: In general I agree, but I don't think we can change this for PHP 7.1. I think many people use this hack to get nullable argument types in PHP < 7.1. They won't be able to use real nullable types unless they require PHP 7.1, which is not realistic. ------------------------------------------------------------------------ [2016-07-14 11:08:26] dmitry@php.net I think, declaration of arguments without default values after the ones with default values - should be prohibited by compiler (at least since PHP-7.1) ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
