I was trying to send japanese email and had a hell of a time getting it to work. I finally stumbled across mb_send_mail() and it did everything I wanted *except* that it only send plain text emails ... sending HTML contents was impossible.
I finally whipped this up. I'm posting in case someone finds it useful.
function send_japanese_mail($to, $subject, $body, $from, $from_email, $is_html_content=false) {
$headers = "MIME-Version: 1.0\\n" ;
$headers .= "From: $from <$from_email>\\n";
$headers .= "Reply-To: $from <$from_email>\\n";
/* If the body is HTML or plain text set the Content-Type header accordingly */
if ($is_html_content) {
$headers .= "Content-Type: text/html;charset=ISO-2022-JP\\n";
/* turn all line breaks into BR tags */
$body = nl2br($body);
}
else {
$headers .= "Content-Type: text/plain;charset=ISO-2022-JP\\n";
}
/* need to convert body to same encoding as stated in Content-Type header above */
$body = mb_convert_encoding($body, "ISO-2022-JP","AUTO");
/* set any sendmail params, optional ... */
$sendmail_params = "-f$from_email";
/*
The subject is actually a "header" and can/will get mangled
if it contains non-ASCII characters. So we need to convert
the subject to something containing only ASCII characters.
First we convert the subject to the same encoding as the
body, then we use mb_encode_mimeheader() to make the subject
line all ASCII characters.
*/
mb_language("ja");
$subject = mb_convert_encoding($subject, "ISO-2022-JP","AUTO");
$subject = mb_encode_mimeheader($subject);
mail($to, $subject, $body, $headers, $sendmail_params);
}
