Edit report at https://bugs.php.net/bug.php?id=76817&edit=1 ID: 76817 Updated by: nikic@php.net Reported by: ildar dot aim at gmail dot com Summary: Can't establish a connection to MySQL after upgrading from 7.2.9 to 7.3.0RC1 Status: Assigned Type: Bug Package: MySQLi related Operating System: archlinux 64 PHP Version: 7.3.0RC1 Assigned To: mysql Block user comment: N Private report: N New Comment: This looks like a different issue from bug #76651, because that one also affects PHP 7.2.9 (which here is said to work correctly). To check for the obvious first, are both PHP versions (PHP 7.2.9 and PHP 7.3.0RC1) using mysqlnd (and not libmysql)?
