What are some common pitfalls when using PHPmailer to connect to an SMTP server?

One common pitfall when using PHPmailer to connect to an SMTP server is not providing the correct SMTP settings, such as the host, port, username, password, and authentication method. This can result in the email not being sent successfully. To solve this issue, make sure to double-check and verify all the SMTP settings before attempting to send an email. 

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