I have following php script through which I can send out email. Now I want to add "CC", copy to another email address, Can somebody give me a hint? Thanks. <html> <head><title>Test email via php</title></head> <body> <?php require_once "Mail.php"; $from = "Sender <[email protected]>"; $to = "Recipient <[email protected]>"; $subject = "This is a test email sent via php"; $body = "This is a test email"; $host = "mail.canadasmallbusiness.org"; $username = "[email protected]"; $password = "**********"; $headers = array ('From' => $from, 'To' => $to, 'Subject' => $subject); $smtp = Mail::factory('smtp', array ('host' => $host, 'auth' => true, 'username' => $username, 'password' => $password)); $mail = $smtp->send($to, $headers, $body); ?> </body> </html>
