mail body not decoded by base64_decode

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,b@mail.com 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, -- View this message in context: http://www.nabble.com/mail-body-not-decoded-by-base64_decode-tp23773646p23773646.html Sent from the PHP - General mailing list archive at Nabble.com.
