I m从事一个PHP/MySQL项目,该项目需要利用多个数据库。 此前,当我只需要查阅一个数据库时,我确定了数据库服务器、用户名称、密码和名称的固定点(DB_SERVER, DB_USER, ect...)。 然而,现在我的申请正在使用多个数据库,我不能再用固定数字来界定这一信息。
我有一个数据库级,处理每当笔书操作时的开关和结关;我的sql_link(DB_SEReck、DB_USER、DB_MAPS)和我的sql_select_db功能均来自这一类别。
根据哪一个数据库,应用需要与哪一个数据库连接,使用超级全球变量确定适当的连接信息是否安全? 我是否应该把链接信息作为论据传递给我的数据库类别? 或者,我是否应该完全重新考虑这一点?
希望提出建议!
如果我把链接信息作为论据传递给我的数据库类别
是的。 数据库班只应了解数据库:如何连接、如何查询等。 配置来源及其即时性不是其业务
