Questions:
    <?php
require_once('../class.phpmailer.php');
//include("../class.smtp.php"); // optional, gets called from within class.phpmailer.php if not already loaded
iconv_set_encoding("internal_encoding", "UTF-8");

$mail             = new PHPMailer();
$mail->CharSet = "utf8";
/*
$body             = file_get_contents('contents.html');
$body             = eregi_replace("[\]",'',$body);
*/
$mail->IsSMTP(); // telling the class to use SMTP
//$mail->Host       = "mail.app-cpr.com"; // SMTP server
//$mail->SMTPDebug  = 2;                     // enables SMTP debug information (for testing)
                                           // 1 = errors and messages
                                           // 2 = messages only
$mail->SMTPAuth   = true;                  // enable SMTP authentication
$mail->SMTPSecure = "tls";                 // sets the prefix to the servier
$mail->Host       = "smtp.gmail.com";      // sets GMAIL as the SMTP server
$mail->Port       = 25;                   // set the SMTP port for the GMAIL server
$mail->Username   = "[email protected]";  // GMAIL username
$mail->Password   = "xxxxxxxxxxx";            // GMAIL password    
$mail->SetFrom('[email protected]', 'First Last');

$mail->AddReplyTo("[email protected]","First Last");

$mail->Subject    = "ทดสอบ";
/*
$mail->AltBody    = "To view the message, please use an HTML compatible email viewer!"; // optional, comment out and test
*/
$mail->MsgHTML("ทดสอบ");

$address = "[email protected]";
$mail->AddAddress($address, "John Doe");

if(!$mail->Send()) {
  echo "Mailer Error: " . $mail->ErrorInfo;
} else {
  echo "Message sent!";
}

?>

The email sending is ok but have a problems with the header.

Subject : ‘ทดสอบ

I will try with
php mail special characters utf8
– use => $mail->Subject = “=?UTF-8?B?”.base64_encode($subject).”?=”;

But it does not work for me. How can I know what is the header coding and solve this to be right in my Thai langauge?

How to&Answers:

Use

$mail->CharSet = 'UTF-8';

instead of

$mail->CharSet = "utf8";
