Question

I read that

All custom headers (like From, Cc, Bcc and Date) are supported

from PHP mail() reference, but how do I actually implement this in my code? i.e. I don’t want any recipient to see the other e-mails… ever.

Something like:

<?php
$to = "[e-mail], [e-mail], [e-mail]";
$subject = "test message";
$msg = "this is a test";
$headers = "Bcc"; // <-- this?

if (mail($to, $subject, $msg, $headers)) 
    echo "message sent";
else 
    echo "uh oh";
?>

Answer 1

Look at the examples on the page.

Here’s one…

$headers .= 'To: Mary <[e-mail]>, Kelly <[e-mail]>' . "\r\n";
$headers .= 'From: Birthday Reminder <[e-mail]>' . "\r\n";
$headers .= 'Cc: [e-mail]' . "\r\n";
$headers .= 'Bcc: [e-mail]' . "\r\n";

So you just add comma separated email addresses after Bcc: in the header.

Here’s one with a loop that will add addresses from the array $recip to BCC:

$headers.="Bcc: "; 
while($count < $count_recip){ 
    $headers.=$recip[$count].", "; 
    $count ++; 
}
