Hello internals! As of today, two weeks have passed since the creation and discussion on the str_contains RFC, without any major controversy. That's why I've updated the RFC status to "Voting". So feel free to submit your vote.
The vote requires a 2/3 majority to be accepted and will end in two weeks from now, which is the 16th March 2020. Link to RFC: https://wiki.php.net/rfc/str_contains Kind regards Philipp Tanlak
