UTF-8 encoding for subject in contact form email

On this sites Website Link contact form I need to send the subject for email in UTF-8.
Where in the code we need to do declare the UTF-8 encoding?

kontakt.php:

<?
require_once "php/sendmail.class.php";
$sendmail = new sendMail();
if ($_SERVER['REQUEST_METHOD'] == 'POST')
{
$sendmail->setParams($_POST);
$sendmail->parseBody();
$sendmail->setHeaders();
if ($sendmail->send())
{
header('Location: kontakt.php?success=1');
}
}
?>


sendmail.class.php:

class sendMail {

var $to = 'email'; // set contact email

var $name = '';
var $subject = '';
var $email = '';
var $body = '';
var $error = array();
var $headers = array();

function setHeaders()
{
$this->headers = "From: $this->email\r\n";
$this->headers.= "MIME-Version: 1.0\r\n";
$this->headers.= "Content-type: text/html; charset=UTF-8\r\n";
}

function parseBody()
{
$message = '<html><body>';
$message .= '<table rules="all" style="border-color: #666;" cellpadding="10">';
$message .= '<tr style="background-color: #eee;"><td><strong>Name:</strong> </td><td>' . $this->name . '</td></tr>';
$message .= "<tr><td><strong>E-Mail-Adresse:</strong> </td><td>" . $this->email . "</td></tr>";
$message .= "<tr><td><strong>Betreff:</strong> </td><td>" . $this->subject . "</td></tr>";
$message .= "<tr><td><strong>Text:</strong> </td><td>" . $this->body . "</td></tr>";
$message .= "</table>";
$message .= "</body></html>";
$this->body = $message;
}

function send()
{
if ($this->error)
{
return FALSE;
}

if (mail($this->to, $this->subject, $this->body, $this->headers))
{
return TRUE;
}
else
{
$this->error[] = 'Fehler beim senden';
return FALSE;
}


In the subject I need the utf 8 german characters encoding. Where do we need to declare it in the code? For the message I found out what to do but for the subject I found no solution.

Answer

here is how i did it:

$head = "From: \"=?ISO-8859-15?Q?".imap_8bit("äöüßÄÖÜ sollte hier gehen")."?=\" <info@mydomain.de>\n";
$subject = "=?ISO-8859-15?Q?".imap_8bit("äöüßÄÖÜ sollte hier gehen")."?=";
mail($mail,$subject,$text,$head);

that is ofc just Latin-15 (German) encoding. utf-8 works the same way: look here for a great explanation on how to use character encoding in mail headers: http://ncona.com/2011/06/using-utf-8-characters-on-an-e-mail-subject/

for your code you have to change this in the sendmail class:

if (mail($this->to, '=?utf-8?B?'.base64_encode($this->subject).'?=', $this->body, $this->headers))

! this only works properly if your php file is utf-8 encoded !

still very annoying. then i switched to phpmailer. that does everything for you. way more easy. i would suggest you use that.
