Hi, PHP replaces dots with underscores for $_GET, $_POST and $_COOKIE. This behavior once made sense because of Register globals. The explanation in the manual also still implies that query and post parameters are converted to variables (see https://php.net/manual/en/language.variables.external.php#language.variables.external.dot-in-names). Register globals has been removed since 5.4.0 and thus this behavior serves little purpose.
I think it would be good to remove the conversion in PHP 8, as it's a general cause of confusion and annoyance for anyone who comes across it. Is there a good reason to keep this behavior in PHP 8?
