How can PHP headers be utilized to ensure proper formatting and display of email content?

To ensure proper formatting and display of email content, PHP headers can be utilized to set the content type to text/html. This tells the email client to interpret the content as HTML, allowing for styling and formatting to be displayed correctly. 

<?php
$to = "recipient@example.com";
$subject = "Testing HTML email";
$message = "<html><body><h1>Hello, this is a test email!</h1></body></html>";
$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";
$headers .= 'From: sender@example.com' . "\r\n";

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