Are there any best practices for handling email copies when using the mail function in PHP?

When sending emails using the mail function in PHP, it is important to handle email copies properly to ensure that the recipient receives the email without any issues. One common best practice is to use the "Bcc" header to send a copy of the email to additional recipients without exposing their email addresses to other recipients. This helps maintain the privacy of all recipients and prevents their email addresses from being shared unintentionally. 

$to = "recipient@example.com";
$subject = "Test Email";
$message = "This is a test email.";

$additional_recipients = "copy1@example.com, copy2@example.com";

$headers = "From: sender@example.com\r\n";
$headers .= "Bcc: " . $additional_recipients . "\r\n";

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