The "i" stands for "improved". The list of improvements can be found in here.
“i”代表“改进”。可以在此处找到改进列表。
MySQLi is the OOP version of MySQL extension. In the end, MySQLi and MySQL accomplish the same thing: they are extension for interacting with MySQL from PHP. A lot of people still use the original MySQL extension instead of the new MySQLi extension because MySQLi requires MySQL 4.1.13+ and PHP 5.0.7+ .
MySQLi 是 MySQL 扩展的 OOP 版本。最后，MySQLi 和 MySQL 完成了同样的事情：它们是从 PHP 与 MySQL 交互的扩展。很多人仍然使用原来的 MySQL 扩展而不是新的 MySQLi 扩展，因为 MySQLi 需要 MySQL 4.1.13+ 和 PHP 5.0.7+ 。
MySQLi supports some things that the old MySQL extension doesn't. Things like prepared statements, multiple statements, and transactions on top of my head.
MySQLi 支持一些旧的 MySQL 扩展不支持的东西。诸如准备好的报表、多个报表和交易之类的事情就在我的脑海中。
