Bug #102095
Updated by Stefan Bürk about 1 year ago
Since PHP 8.3RC3 8.3 beta 3 [1] the `\IntlDateFormatter` throws a `\IntlException` exception with the message: datefmt_create: invalid locale: U_ILLEGAL_ARGUMENT_ERROR if a invalid locale is passed to the constructor. The value `C` is considered as a non valid locale, albeit it may be set. See: https://github.com/php/php-src/commit/a80db7b52aa134bdc8b9841
