What are some best practices for organizing and setting PDO attributes in PHP for optimal performance and reliability?

When working with PDO in PHP, it is important to properly set attributes for optimal performance and reliability. Some best practices include setting error mode to exceptions for easier error handling, enabling emulation mode to avoid potential SQL injection attacks, and setting the fetch mode to ensure consistent data retrieval. 

// Create a PDO connection with optimal attributes set
$dsn = 'mysql:host=localhost;dbname=mydatabase';
$username = 'username';
$password = 'password';

try {
    $pdo = new PDO($dsn, $username, $password);
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    $pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
    $pdo->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE, PDO::FETCH_ASSOC);
} catch (PDOException $e) {
    echo 'Connection failed: ' . $e->getMessage();
}
