if you want to prevent error from being shown just put this line on top level of your code: error_reporting(~E_ALL);

try this on your local but not in sololearn playground: <?php $db = []; $db['db_host'] = 'localhost'; $db['db_user'] = 'root'; $db['db_pass'] = ''; $db['db_name'] = 'cms'; foreach ($db as $key => $values){ define(strtoupper($key), $values); } $connection = mysqli_connect( DB_HOST, DB_USER, DB_PASS, DB_NAME ); if($connection ){ echo "connected"; } ?>

and the reason why it's always show connected because mysqli_connect function always return an object of type mysqli: http://php.net/manual/en/mysqli.construct.php#refsect1-mysqli.construct-returnvalues
