To understand and troubleshoot PDO usage in PHP, it is recommended to refer to the official PHP documentation on PDO (https://www.php.net/manual/en/book.pdo.php) as well as online tutorials and guides. Additionally, checking for error messages and using tools like var_dump() to inspect variables can help in identifying and resolving issues. 

try {
    $pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    echo "Connection failed: " . $e->getMessage();
