Are there any best practices for creating dynamic mailto links in PHP, especially within a Joomla 2.5 site?

When creating dynamic mailto links in PHP within a Joomla 2.5 site, it is important to properly sanitize and validate user input to prevent any potential security vulnerabilities. One way to achieve this is by using Joomla's built-in input filtering functions to sanitize the email address before constructing the mailto link. Additionally, you can use Joomla's JFactory class to get the current user's email address if needed. 

// Get the user's email address from Joomla's JFactory class
$user = JFactory::getUser();
$email = $user->email;

// Sanitize and validate the email address
$email = filter_var($email, FILTER_SANITIZE_EMAIL);

// Construct the dynamic mailto link
$mailtoLink = '<a href="mailto:' . $email . '">Send Email</a>';

echo $mailtoLink;
