How can PHP developers ensure that emails sent using the mail function are stored in the webmail sent folder for future reference?

To ensure that emails sent using the mail function are stored in the webmail sent folder for future reference, PHP developers can add the "Reply-To" header to the email with the sender's email address. This will trick the webmail client into thinking that the email was sent from the sender's email address, thus storing it in the sent folder. 

$to = "recipient@example.com";
$subject = "Subject";
$message = "Message body";
$headers = "From: sender@example.com\r\n";
$headers .= "Reply-To: sender@example.com\r\n";

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