How can PHP beginners ensure the security of email addresses when sending emails to multiple recipients individually?

To ensure the security of email addresses when sending emails to multiple recipients individually, PHP beginners can use the BCC (Blind Carbon Copy) feature to hide the email addresses of other recipients. By using BCC, each recipient will receive the email as if it was sent only to them, thus keeping their email address private. 

$to = 'recipient1@example.com';
$subject = 'Subject';
$message = 'Message';

$headers = 'From: sender@example.com' . "\r\n";
$headers .= 'Bcc: recipient2@example.com, recipient3@example.com' . "\r\n";

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