What are some alternative approaches or resources to troubleshoot connection issues with Gmail in PHP?

If you are experiencing connection issues with Gmail in PHP, one alternative approach is to use OAuth2 authentication instead of username and password. This can provide a more secure and reliable connection to Gmail's API. Additionally, you can check for any firewall or network restrictions that may be blocking the connection to Gmail servers. 

// Example code snippet using OAuth2 authentication for Gmail connection

require_once 'vendor/autoload.php';

$client = new Google_Client();
$client->setAuthConfig('credentials.json');
$client->addScope(Google_Service_Gmail::GMAIL_READONLY);

// Set up the Gmail service
$service = new Google_Service_Gmail($client);

// Make API requests using the $service object
