What are the differences between sending a plain-text email and an HTML-formatted email in PHP?

When sending a plain-text email in PHP, the content of the email is simple text without any formatting or styling. On the other hand, when sending an HTML-formatted email, the content can include HTML tags for formatting, images, links, and styling. To send an HTML-formatted email in PHP, you need to set the appropriate headers and use the `mail()` function with the HTML content included. 

$to = "recipient@example.com";
$subject = "HTML Email Test";
$message = "<html><body><h1>Hello, this is a test HTML email!</h1><p>This is the content of the email.</p></body></html>";
$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";

mail($to, $subject, $message, $headers);
