Problems with PHP Mailer header encoding - php

Question

<?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 = "xxxxxxx#gmail.com"; // GMAIL username
$mail->Password = "xxxxxxxxxxx"; // GMAIL password
$mail->SetFrom('xxxxxxx#gmail.com', 'First Last');
$mail->AddReplyTo("xxxxxxx#gmail.com","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 = "xxxxxxx#gmail.com";
$mail->AddAddress($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?

Answer 1

Use
$mail->CharSet = 'UTF-8';
instead of
$mail->CharSet = "utf8";
