PHP - Send HTML and plain Text email doesn't work in Gmail

Question

Could you explane me what is wrong in this simple code?
It doesn't work with Gmail but yes with some other clients.

$boundary = md5( uniqid() . microtime() );
$to      =  $user;
$headers[] = 'From: my@email.com';
$headers[] = 'MIME-Version: 1.0';   
$headers[] = 'Content-Type: multipart/alternative; boundary="'.$boundary.'"\r\n';
$subject = "The subject";
$message = "--" . $boundary . "\r\n";
$message .= "Content-type: text/plain; charset=utf-8\r\n";
$message .= "Content-Transfer-Encoding: 8bit\r\n\r\n"; 
$message .= 'Simple Text Message line 1\r\nline 2\r\nline 3';
$message .= "\r\n\r\n--" . $boundary . "\r\n";
$message .= "Content-type: text/html; charset=utf-8\r\n";
$message .= "Content-Transfer-Encoding: 8bit\r\n\r\n";
$message .= "<h1>html message!</h1>";
$message .= "\r\n\r\n--" . $boundary . "--";
mail($to, $subject, $message, implode("\r\n", $headers))

In Gmail I get something like this:

--05fd97038918d12debb49153b3ad67a5
Content-type: text/plain; charset=utf-8
Content-Transfer-Encoding: 8bit

Simple Text Message line 1\r\nline 2\r\nline 3

--05fd97038918d12debb49153b3ad67a5
Content-type: text/html; charset=utf-8
Content-Transfer-Encoding: 8bit

<h1>html message!</h1>

--05fd97038918d12debb49153b3ad67a5--

Luca, have you tried the suggestion/solution found here: https://stackoverflow.com/questions/712392/send-email-using-the-gmail-smtp-server-from-a-php-page ? — Rushikumar, Jun 01 '17 at 15:20
Thanks for suggestion, but i prefer don't use external libraries. Can i do the same without libraries? — Luca4k4, Jun 01 '17 at 15:30
Regardless, did you check this? https://stackoverflow.com/questions/10028428/using-core-php-mail-to-send-via-gmail-smtp — Rushikumar, Jun 01 '17 at 17:12
I don't understand: why i can't send a mail html/simple text to Gmail with php mail() but the email only html and only simple text yes? nonsense — Luca4k4, Jun 01 '17 at 18:36
