Adding CC in PHP mail function - php

Question

I want to send mail with CC. The email is sent successfully, but CC is not sent.
$to = 'abc#xyz.com';
$subject = 'Order Details of Order Number:'.$orderID;
$headers = "From: webmaster#xyz.com\r\nReply-To: webmaster#xyz.com";
$headers .= "\r\nContent-Type: multipart/alternative; boundary=\"PHP-alt-".$random_hash."\"";
$message = "Test Message";
$headers .= 'Cc: def#xyz.com' . "\r\n";
mail($to, $subject, $message, $headers);
I am sending this mail as HTML.

Answer 1

Add the header as following,
$to = 'toemailaddress#testcom';
$from = 'fromemail#from.com';
$fromName = 'FromName';
$subject = "Email Subject";
$htmlContent = "<h> content of the email </h>";
$headers = "From: $fromName" . " <" . $from . ">" . "\r\n";
$headers .= "Cc: cc#cc.com ";
$semi_rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";
//multipart boundary
$message = "--{$mime_boundary}\n" . "Content-Type: text/html; charset=\"UTF-8\"\n" ."Content-Transfer-Encoding: 7bit\n\n" . $htmlContent . "\n\n";
$returnpath = "-f" . $from;
$message .= "--{$mime_boundary}--";
$mail = #mail($to, $subject, $message, $headers, $returnpath);

Answer 2

Try add this code in the following order:
$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: <info#premierinspectiontn.com>\r\n";
//add boundary string and mime type specification
$headers .= "Content-Type: multipart/mixed; boundary=\"PHP-mixed-".$random_hash."\"";
