php 5.4不支持引用变量,严格标准：只能通过引用PHP 5.4分配变量

我升级MyPHP版本到5.4(Xampp 1.7.3到1.8.0)。现在我看到Strict Standards错误，对于myDBconnection：

Strict Standards: Only variables should be assigned by reference in C:\xampp\htdocs\alous\include\dbconn.php on line 4

dbconn.php：

defined('_VALID') or die('Restricted Access!');

$conn = &ADONewConnection($config['db_type']); //

if ( !$conn->Connect($config['db_host'], $config['db_user'], $config['db_pass'], $config['db_name']) ) {

echo 'Could not connect to mysql! Please check your database settings!';

die();

}

$conn->execute("SET NAMES 'utf8'");

?>

注意：我不需要使用此方法禁用php.ini中的严格标准error_reporting = E_ALL& 〜E_NOTICE& 〜E_STRICT！我想修复我的PHP代码。
