The only reason I've taken this approach is for developers using type checking to identify certain mistakes in their code (which can be useful); so I wanted to keep them happy by not changing any of the stricter "string only" arguments... that's why my patch silently makes PHP a bit more tolerant of NULL for the projects that aren't using strict_types... and, as noted before, I'm not suggesting all arguments - e.g. NULL is quite likely a bug for the $characters argument in trim(), and PHP probably should complain, even though an empty string does not. If there's an argument to be made to rewiden a type to include null, make > that case and have that debate on a function by function basis. I'm fine with that, but I worry people are underestimating the size of the problem (having a debate on each one would take a long time). I've put together my proposed list, it took a few days, and a lot of thought: https://github.com/craigfrancis/php-allow-null-rfc/blob/main/functions-change.md I've asked for suggestions and pull requests a few times, and the best I've got is $path/$domain for setcookie() (I disagree because NULL is often used for those arguments, so that $secure and $httponly can be set to true). At this point I think people should be suggesting why any of these function arguments should trigger a Fatal Error in PHP 9 if they receive NULL.. again, happy to discuss here; or off-list via email, video call, etc (thankfully, for my own mental health, the off-list messages have been positive)... or you can make suggestions on the repo: https://github.com/craigfrancis/php-allow-null-rfc/issues https://github.com/craigfrancis/php-allow-null-rfc/pulls
