What is the PDO library in php

illustrate

1. It can support 12 different types of database drivers, so PDO has received more praise.

2. PDOs have other features that make them a better choice for most developers.

PDO connection

The first is to connect to the database. Since PDO is completely object-oriented, we will use the PDO class example.

All you need to do is define the host, database name, username, password and database character set.

 $host = 'localhost';
$db = 'theitstuff';
$user = 'root';
$pass = 'root';
$charset = 'utf8mb4';
$dsn = "mysql:host=$host;dbname=$db;charset=$charset";
$conn = new PDO($dsn, $user, $pass);

The above is an introduction to the PDO library in php. I hope it will be helpful to everyone.
