Mail() wrong encoding?

Question

PHP

Hello, I send the form to the mail with the following code

if (isset($_POST['send1'])) {

      $body = "Форма обратной связи \r\n\r\nИмя: ".$_POST['name']."\r\nТелефон: ".$_POST['phone'];

      $subject = "Форма обратной связи CellGSM";

      $adress = '[email protected]';

      mail($adress, $subject, $body);

            echo "<center><h1>Мы с вами свяжемся :)</h1></center>";

    
    }

But the Cyrillic alphabet comes to the mail in this form:
Phone: ���ñ

Answer 1

Good evening.
Add a header that will specify the desired encoding.

$headers .= "Content-type: text/html; charset=\"utf-8\"\n";

Answer 2

Because it is necessary to comply with the RFC www.faqs.org/rfcs/rfc2047.html
In order not to reinvent the wheel, use ready-made libraries. For example pear.php.net/package/Mail_Mime , https://github.com/PHPMailer/PHPMailer or similar

Answer 3

You need to use libraries to send emails, then there will be no problems.
For example PHPMailer or swiftmailer.org
