How can the PHPmailer object be effectively utilized to check for successful SMTP connection?

To check for a successful SMTP connection using the PHPmailer object, you can utilize the `SMTPDebug` property with a value of `2`. This will enable debugging output to be displayed, including the SMTP conversation. By examining this output, you can verify if the connection was successful or if there are any errors. 

use PHPMailer\PHPMailer\PHPMailer;

// Create a new PHPMailer object
$mail = new PHPMailer();

// Enable debugging output
$mail->SMTPDebug = 2;

// Set SMTP settings
$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->Port = 587;
$mail->SMTPAuth = true;
$mail->Username = 'your_username';
$mail->Password = 'your_password';

// Check for successful SMTP connection
if(!$mail->smtpConnect()){
    echo 'SMTP connection failed.';
} else {
    echo 'SMTP connection successful.';
}
