What are the common challenges faced when trying to extract HTML emails using PHP?

One common challenge when trying to extract HTML emails using PHP is properly parsing the email content to extract the HTML portion. This can be challenging because emails often contain multipart content with both HTML and plain text versions. To solve this, you can use PHP libraries like PHPMailer or Zend Mail to easily parse and extract the HTML content from emails. 

// Example using PHPMailer to extract HTML content from an email
use PHPMailer\PHPMailer\PHPMailer;

// Load the email content
$emailContent = file_get_contents('email.eml');

// Create a new instance of PHPMailer
$mail = new PHPMailer();
$mail->msgHTML($emailContent);

// Extract the HTML content
$htmlContent = $mail->Body;

echo $htmlContent;
