What are the differences between implementing clickable email addresses and URLs in PHP tables?

When displaying email addresses or URLs in PHP tables, it is important to make them clickable for easy navigation. To implement clickable email addresses, use the "mailto:" prefix before the email address. For URLs, use the "http://" or "https://" prefix before the URL. This will create clickable links that users can click on to open their email client or browser.

// Example of implementing clickable email addresses in a PHP table
$email = "example@example.com";
echo "<td><a href='mailto:$email'>$email</a></td>";

// Example of implementing clickable URLs in a PHP table
$url = "http://www.example.com";
echo "<td><a href='$url'>$url</a></td>";
