Hi, I came from php-src.

The following issue has been reported in php-src:
https://github.com/php/php-src/issues/13628

I think that the "info" of OK_packet returned by Protocol::AuthSwitchResponse has probably changed since 11.4.
https://dev.mysql.com/doc/dev/mysql-server/latest/page_protocol_connection_phase_packets_protocol_auth_switch_response.html
https://dev.mysql.com/doc/dev/mysql-server/latest/page_protocol_basic_ok_packet.html

Until 11.3.2, this value was empty, but since 11.4 it contains a random-looking string.

If this is the intended change, I would like to do something about it on the php side, but since it is not "human readable status information" as stated in the protocol description, I am having trouble deciding.

It would be helpful if you could tell us about this change.

Regards.
