What are the differences between PDO, PDO_MySQL, and MySQLi in terms of database communication and performance?

When it comes to database communication and performance in PHP, PDO, PDO_MySQL, and MySQLi are all popular choices. PDO is a database access layer that provides a consistent interface for accessing different types of databases, while PDO_MySQL is a specific PDO driver for MySQL databases. MySQLi is a PHP extension that provides a procedural and object-oriented interface for interacting with MySQL databases. In terms of performance, MySQLi is generally faster than PDO due to its more direct connection to the MySQL database. 

// Example code using MySQLi to connect to a MySQL database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database_name";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
