What are the differences between MySQL and MySQLi in PHP, and how can one effectively transition from one to the other?

MySQLi (MySQL Improved) is a newer and more feature-rich extension for interacting with a MySQL database in PHP compared to the older MySQL extension. To transition from MySQL to MySQLi, you need to update your database connection code and queries to use MySQLi functions and methods. 

// MySQL connection using MySQLi
$mysqli = new mysqli('localhost', 'username', 'password', 'database');

// Check connection
if ($mysqli->connect_error) {
    die("Connection failed: " . $mysqli->connect_error);
}

// MySQL query using MySQLi
$result = $mysqli->query("SELECT * FROM table");

// Fetch data
while ($row = $result->fetch_assoc()) {
    // Process each row
}

// Close connection
$mysqli->close();
