What is the significance of using ob_end_clean() in the context of PHPMailer and attachment handling?

When working with PHPMailer and handling attachments, it's important to use ob_end_clean() to clear any output buffers before sending the email. This ensures that the attachment data is not corrupted by any previous output generated by the script. 

// Clear any output buffers before sending the email with attachments
ob_end_clean();

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

// Add attachments to the email
$mail->addAttachment('path/to/file1.pdf');
$mail->addAttachment('path/to/file2.jpg');

// Send the email
$mail->send();
