How can PHP developers ensure that email links function properly for recipients without the need for server-side link assignment on an external SMTP server?

PHP developers can ensure that email links function properly for recipients by using absolute URLs in the email content. This way, the links will work regardless of the recipient's email client or settings. By including the full URL in the email message, there is no need for server-side link assignment on an external SMTP server. 

<?php
$recipient_email = "recipient@example.com";
$subject = "Check out our latest offers!";
$message = "Click <a href='https://www.example.com/offers'>here</a> to view our latest offers.";

$headers = "From: sender@example.com\r\n";
$headers .= "Content-type: text/html\r\n";

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