用代码如何知道当前正在使用的哪个数据库?,当前数据库

  有一天生产环境突然发生了一个错误,抛出的异常大概是某某表不存在,我当时就想怎么会不存在呢?不会是受到黑客的攻击了吧?所以就想知道当前使用的哪一个数据库

<span>$current_database</span> = <span>mysql_query</span>("SELECT DATABASE()") or <span>die</span>(<span>mysql_error</span>());<br /><span>echo</span> <span>mysql_result</span>(<span>$current_database</span>,0);
Copy after login
