Openshift中的PHP MySQL 5.5 db连接

我对openshift和这些git,ssh编程很新.到目前为止我开发了这么多.
安装 PHP 5.3,MysqL 5.5,PHPMyAdmin 4.0墨盒

这是我在PHP中的dbcon文件.
基本上我需要将我的PHP应用程序与openshift MysqL db连接.这就是我所做的.

<?PHP

// Database Connection Setting

$dbhost = "127.0.0.1"; // Host name 
$dbport = "3308"; // Host port
$dbusername = "user"; // MysqL username 
$dbpassword = "pass"; // MysqL password 
$db_name = "mf"; // Database name 

$MysqLCon = MysqLi_connect($dbhost,$dbusername,$dbpassword,"",$dbport) or die("Error: " . MysqLi_error($MysqLCon));
MysqLi_select_db($MysqLCon,$db_name) or die("Error: " . MysqLi_error($MysqLCon));
?>

这给了我一个关于openshift的错误,但适用于其他PHP应用程序.我的错误解释没有得到任何错误：{…空格…}.

你能救我一下吗？

非常感谢你的努力.之前没有抛出视觉错误.但是我这样做是为了让它发挥作用.

define('DB_HOST',getenv('OPENSHIFT_MysqL_DB_HOST'));

$dbhost = constant("DB_HOST"); // Host name
