 > Looking at [https://core.trac.wordpress.org/browser/tags/5.6/src/wp-
 includes/wp-db.php#L1684 the code in WordPress], unless `WP_DEBUG` mode is
 enabled, the `@` operator preceded the `mysql_connect()` call. In previous
 versions of PHP, it's likely that this just failed silently, and just
 happened to work on accident.

 Since the error is now more prominent with PHP 8, I think we could display
 a better error message here for clarity, with some action items for the
 user to check, and a link to support forums.
