What are the best practices for handling authentication errors, such as "invalid_grant," when working with OneDrive in PHP?

When handling authentication errors like "invalid_grant" when working with OneDrive in PHP, the best practice is to catch the error and prompt the user to re-authenticate or refresh their access token. This error typically occurs when the access token has expired or is no longer valid. 

try {
    // Code to interact with OneDrive API
} catch (Exception $e) {
    if ($e->getCode() == 'invalid_grant') {
        // Prompt the user to re-authenticate or refresh their access token
        echo 'Authentication error: Please re-authenticate.';
    } else {
        // Handle other exceptions
        echo 'An error occurred: ' . $e->getMessage();
    }
}
