Question

我正在使用此功能在我的邮件中附加pdf。它工作正常但是当用户试图打开pdf文件时，他收到一条消息，告诉他文件无法打开，因为文件格式化问题。

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

        // carriage return type (we use a PHP end of line constant)
        $eol = "\r\n";

        // attachment name
        $filename = $invoice.'.pdf';

        // encode data (puts attachment in proper format)
        $attachment = chunk_split(base64_encode($filename));
        //$attachment = $filename;

        // main header
        $from     = "test@productionserver.in";
        $headers  = "From: ".$from.$eol;
        $headers .= "MIME-Version: 1.0".$eol; 
        $headers .= "Content-Type: multipart/mixed; boundary=\"".$separator."\"".$eol;

        // no more headers after this, we start the body! //
        $body = "--".$separator.$eol;
        $body .= "Content-Transfer-Encoding: 7bit".$eol.$eol;


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

        // attachment
        $body .= "--".$separator.$eol;
        $body .= "Content-Type: application/octet-stream; name=\"".$filename."\"".$eol; 
        $body .= "Content-Transfer-Encoding: base64".$eol;
        $body .= "Content-Disposition: attachment".$eol.$eol;
        $body .= $attachment.$eol;
        $body .= "--".$separator."--";

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

有没有人知道我做错了什么？

Answer 1

$attachment = chunk_split(base64_encode($filename));

您正在将文件名编码为附件。您需要对实际的文件进行编码，而不仅仅是其名称。

$attachment = chunk_split(base64_encode(file_get_contents($filename)));

在电子邮件功能中发送附件但无法获取
