What are the advantages of transitioning from using MySQL functions in PHP to utilizing mysqli or PDO for database interactions?

Transitioning from using MySQL functions in PHP to mysqli or PDO for database interactions offers several advantages, including improved security through prepared statements to prevent SQL injection attacks, support for parameter binding, and the ability to work with multiple database types. Additionally, mysqli and PDO provide object-oriented interfaces for more efficient and flexible code. 

// Using mysqli for database interactions
$mysqli = new mysqli("localhost", "username", "password", "database");

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

$query = $mysqli->prepare("SELECT * FROM users WHERE id = ?");
$id = 1;
$query->bind_param("i", $id);
$query->execute();
$result = $query->get_result();

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

$query->close();
$mysqli->close();
