Hi,
I want to introduce my new RFC on adding Locale::getDisplayKeyword() and Locale::getDisplayKeywordValue() to the intl extension, see [1]. This fills in the little gap between ICU API and php interface, as every getdisplay* ICU API has a corresponding php inferface without uloc_getDisplayKeywordValue and uloc_getDisplayKeyword. Take care, Weilin Du [1]: https://wiki.php.net/rfc/getdisplaykeyword_and_getdisplaykeywordvalue
