Why are there two different types, what is the need for the difference?

推荐答案

一个用于过程式编程，另一个用于 OOP 式编程.两者都有相同的目的；打开一个到 MySQL 服务器的新连接

One is for Procedural style programming and other is for OOP style programming. Both serve the same purpose; Open a new connection to the MySQL server

OOP 样式用法

$mysqli = new mysqli('localhost', 'my_user', 'my_password', 'my_db');

程序风格的使用

$link = mysqli_connect('localhost', 'my_user', 'my_password', 'my_db');

参考:PHP手册
