php使用Mail()函数发送带附件的邮件

您可以尝试使用以下代码：

    $filename = \'myfile\';
    $path = \'your path goes here\';
    $file = $path . \"/\" . $filename;

    $mailto = \'mail@mail.com\';
    $subject = \'Subject\';
    $message = \'My message\';

    $content = file_get_contents($file);
    $content = chunk_split( 64_encode($content));

    // a random hash will be necessary to send mixed content
    $separator = md5(time());

    // carriage return type (RFC)
    $eol = \"\\r\\n\";

    // main header (multipart mandatory)
    $headers = \"From: name <test@test.com>\" . $eol;
    $headers .= \"MIME-Version: 1.0\" . $eol;
    $headers .= \"Content-Type: multipart/mixed; boundary=\\\"\" . $separator . \"\\\"\" . $eol;
    $headers .= \"Content-Transfer-Encoding: 7bit\" . $eol;
    $headers .= \"This is a MIME encoded message.\" . $eol;

    // message
    $body = \"--\" . $separator . $eol;
    $body .= \"Content-Type: text/plain; charset=\\\"iso-8859-1\\\"\" . $eol;
    $body .= \"Content-Transfer-Encoding: 8bit\" . $eol;
    $body .= $message . $eol;

    // attachment
    $body .= \"--\" . $separator . $eol;
    $body .= \"Content-Type: application/octet-stream; name=\\\"\" . $filename . \"\\\"\" . $eol;
    $body .= \"Content-Transfer-Encoding:  64\" . $eol;
    $body .= \"Content-Disposition: attachment\" . $eol;
    $body .= $content . $eol;
    $body .= \"--\" . $separator . \"--\";

    //SEND Mail
    if (mail($mailto, $subject, $body, $headers)) {
        echo \"mail send ... OK\"; // or use booleans here
    } else {
        echo \"mail send ... ERROR!\";
        print_r( error_get_last() );
    }
