Are there any best practices for handling HTML emails retrieved via IMAP in PHP to ensure only the message content is displayed?

When retrieving HTML emails via IMAP in PHP, it's important to sanitize the message content to ensure that only safe HTML is displayed to prevent any potential security vulnerabilities. One way to achieve this is by using a HTML purifier library that can filter out any potentially harmful content such as scripts or malicious code. 

// Include the HTMLPurifier library
require_once 'path/to/HTMLPurifier.auto.php';

// Retrieve the email message content
$emailContent = $email->getBody();

// Create a new HTMLPurifier instance
$config = HTMLPurifier_Config::createDefault();
$purifier = new HTMLPurifier($config);

// Sanitize the email content
$sanitizedContent = $purifier->purify($emailContent);

// Display the sanitized content
echo $sanitizedContent;
