When handling errors in PHP code, it is important to catch exceptions and handle them appropriately to prevent the script from crashing and to provide meaningful feedback to the user. In the provided example with the PDO exception catch block, it is recommended to log the error message for debugging purposes and display a user-friendly error message on the front end.

    // PDO database connection code here
} catch (PDOException $e) {

    error_log('PDO Exception: ' . $e->getMessage());

    // Display a user-friendly error message
    echo 'An error occurred. Please try again later.';
}
