In order to have these functions available, you must compile PHP with
support for the mysqli extension.
MySQL 8
When running a PHP version before 7.1.16, or PHP 7.2 before 7.2.4, set
MySQL 8 Server's default password plugin to mysql_native_password
or else you will see errors similar to
The server requested authentication method unknown to the client [caching_sha2_password]
even when caching_sha2_password is not used.
This is because MySQL 8 defaults to caching_sha2_password, a plugin that is
not recognized by the older PHP (mysqlnd) releases. Instead, change it by
setting default_authentication_plugin=mysql_native_password
in my.cnf. The caching_sha2_password
plugin will be supported in a future PHP release. In the meantime, the
mysql_xdevapi extension does
support it.
