]
];

$dsn = "mysql:host=".$db['settings']['host'].";dbname=".$db['settings']['base'].";charset=".$db['settings']['char']."";
$opt = [
PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC,
PDO::ATTR_EMULATE_PREPARES => false,
];
$go = new PDO($dsn, $db['settings']['user'], $db['settings']['pass'], $opt);
if($go -> connect_errno) die('ERROR -> '.$go -> connect_error);
