Add BCC parameter to mail()

Hi folks - Newbie question... Q: Is there a way to add BCC and/or CC parameters to this simple email function? If there is a better way to do this - please let me know.... Thanks in advance.... <?php $Name = "test"; //senders name $email = "test@test.com"; //senders e-mail adress $recipientname = "test"; $recipient = "joe@test.com"; //recipient $mail_body = "test"; $subject = "test"; $header = "From: ". $Name . " <" . $email . ">\r\n"; //optional headerfields $fullto = $recipientname . " <" . $recipient . ">"; ini_set('sendmail_from', 'test@test.com'); mail($fullto, $subject, $mail_body, $header); //mail command :) ?> Thanks, cool@hosting4days.com
