mail body not decoded by base64_decode

[cuongvt]

Hi all

I'm using below function to send Japanese mail, mail clients such as outlook etc displayed Japanese text withou problems but if I viewed JP mail via web-based mail such as Gmail, the JP subject is normally displayed, however the JP body still base64 encoded strings, it still was not decoded yet.

Could anyone tell me solution to solve this?

=======================================

private static function _sendPc( $from, $to, $subject, $body, $contentType, $charSet="shift_jis", $header="", $parameter=""){

Debugger::snap();

//make header

$headers  = "From: $from\n";

$headers .= "MIME-Version: 1.0\n";

$headers .= "Content-type: $contentType; charset=ISO-2022-JP\n";

//$headers .= "Content-type: $contentType; charset=SHIFT_JIS\n";

//$headers .= "Content-Transfer-Encoding: base64";

$headers .= "Content-Transfer-Encoding: quoted-printable";

 

 

// add header to mail

if( strlen( $header ) > 0 ){

$headers .= "\n";

$headers .= $header;

}

 

//make parameter

$parameters = $parameter;

 

//make subject

$subject = '=?ISO-2022-JP?B?'.base64_encode(mb_convert_encoding($subject, 'ISO-2022-JP', 'AUTO' )).'?=';

//$subject = '=?SHIFT_JIS?B?'.base64_encode($subject).'?=';

//$body = base64_encode($body);

$body = mb_convert_encoding( $body, 'ISO-2022-JP', "AUTO");

 

// a,[email protected] こんなEMAILアドレスがたまにあるための回避策

$pos1 = strpos($to, ",");

$pos2 = strpos($to,"<");

if( $pos1 !== FALSE && $pos2 === FALSE ){

$to = "<" . $to .">";

}

 

if( $parameters != null && strlen( $parameters ) > 0 )

mail( $to, $subject, $body, $headers, $parameters );

else

mail( $to, $subject, $body, $headers,"-f" . $from );

 

Debugger::debug( "sended" );

return true;

}

 

Thanks and regards,
