php - new mysqli vs mysqli_connect

Question

What is difference between the new mysqli and mysqli_connect? I know that executing a query is different;
for example: mysqli->query() and mysqli_query()
Why are there two different types, what is the need for the difference?

Answer 1

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 Style usage

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

Procedural Style usage

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