How can one ensure consistent email display across different email clients when using PHP?

To ensure consistent email display across different email clients when using PHP, it is important to use inline CSS, avoid using external stylesheets, and test the email template in various email clients before sending it out. 

<?php
$to = 'recipient@example.com';
$subject = 'Test Email';
$message = '<html><body><div style="color: #333; font-size: 16px;">This is a test email.</div></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);
?>
