Note Submitter: boukeversteegh at gmail dot com ---- (php 5.3.3) If $port is a string, such as "3306", mysqli::query() will not work, even though mysqli_connect_errno() reports no error (value 0)! <?php $mysqli = new mysqli("localhost", "user","password","database", "3306"); //port is a string! $mysqli->query("SELECT 1;")->fetch_assoc(); // Fatal error: Call to a member function fetch_assoc() on a non-object ?> This is particularly strange, since mysqli::query() should return a result object, or a boolean. So, be careful when you read your port from a string or config file. Cast it to int first: <?php $port = (int)$port; ?>
