We support ASCII case-insensitivity. Of course, this supports your "let's drop case insensitivity" position on the grounds that our implementation of it is ironically parochial and terrible.
The argument about Turkish becomes irrelevant though since any constant declared with a non-english identifier is (at least partially) forced to be case-sensitive by virtue of our non-localized tolower implementation. https://3v4l.org/Od03d -Sara -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
