PHP insert cc into mail function [duplicate]

Answer 1

just tested this, and it worked as expected:

$headers .= 'Cc: test@test.com\r\n';
$headers .= 'Bcc: test@test.com\r\n';

I would also suggest moving your carriage return and new line to the end of the previous entry to $headers

$headers = "From: $from_email\r\nReply-To: $from_email";
$headers .= 'Cc: test@test.com\r\n';
$headers .= 'Bcc: test@test.com\r\n';
$headers .= "Return-Path: \r\n";

// add boundary string and mime type specification
$headers .= "Content-Type: multipart/mixed; boundary=\"PHP-mixed-".$random_hash."\"";

hope that helps
