What are the advantages of using PDO for database connections in PHP, as demonstrated in the revised code snippet in the forum thread?

Issue: The original code snippet in the forum thread uses the outdated `mysql_*` functions for database connections in PHP, which are deprecated and no longer recommended due to security vulnerabilities and lack of support. To address this issue, it is recommended to use PDO (PHP Data Objects) for secure and flexible database connections in PHP. 

// Revised code snippet using PDO for database connections
try {
    $pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch (PDOException $e) {
    die("Error connecting to database: " . $e->getMessage());
}

// Example query using prepared statement
$stmt = $pdo->prepare("SELECT * FROM users WHERE id = :id");
$stmt->execute(['id' => 1]);
$user = $stmt->fetch(PDO::FETCH_ASSOC);

// Displaying user data
echo "User ID: " . $user['id'] . "<br>";
echo "Username: " . $user['username'] . "<br>";
echo "Email: " . $user['email'] . "<br>";

// Close the database connection
$pdo = null;
