Question

我有一个pdo脚本，它是一个基本的登录脚本。它在我的测试服务器上工作得很好。但在我的直播服务器上没有功能。我收到了PDO错误：

PHP致命错误：未捕获的异常＆＃39; PDOException＆＃39;消息＆＃39; SQLSTATE [3D000]：无效的目录名称：1046未选择数据库＆＃39;在/nas/content/live/inboundpro/leadportal/index.php:40\nStack trace：\ n＃0 /nas/content/live/inboundpro/leadportal/index.php(40）：PDOStatement-＆gt; execute（） \ n＃1 {main} \ n在第40行的/nas/content/live/inboundpro/leadportal/index.php中抛出，引用者：http://www.inboundprospect.com/leadportal/

    try {

我错过了什么？
