为什么我们通过电子邮件发送的pdf文件不能打开？

php Why pdf which we send on email not open?(为什么我们通过电子邮件发送的pdf文件不能打开？)

问题描述

            $NameFile = '15_10_2014_.pdf';
            $File = './TEMP/15_10_2014_.pdf';
            $to = 'test2@test.com';
            $From = "test@test.com";

        $EOL = "
"; 
        $boundary     = "--".md5(uniqid(time()));
        $message = "
        <p>TEXT TEXT TEXT</p>
        ";
        $subject= '=?utf-8?B?' . base64_encode('Счет на оплату') . '?=';

        $headers    = "MIME-Version: 1.0;$EOL";   
        $headers   .= "Content-Type: multipart/mixed; boundary="$boundary"$EOL";  
        $headers   .= "From: $From
Reply-To: $From
";  

        $multipart  = "--$boundary$EOL";   
        $multipart .= "Content-Type: text/html; charset=utf-8$EOL";   
        $multipart .= "Content-Transfer-Encoding: base64$EOL";   
        $multipart .= $EOL;
        $multipart .= chunk_split(base64_encode($message));   

        $multipart .=  "$EOL--$boundary$EOL";   
        $multipart .= "Content-Type: application/octet-stream; name="$NameFile"$EOL";   
        $multipart .= "Content-Transfer-Encoding: base64$EOL";   
        $multipart .= "Content-Disposition: attachment; filename="$NameFile"$EOL";   
        $multipart .= $EOL; 
        $multipart .= chunk_split(base64_encode($File));   

        $multipart .= "$EOL--$boundary--$EOL";   

        if(!mail($to, $subject, $multipart, $headers)){
            $content = $this->return_error_p('Mail not send');
        }
        else{
            $content = $this->return_true_p('Mail send');
        }

结果，我们收到了一封带有pdf附件的电子邮件，但该pdf文件没有打开。打开文件时，我们收到错误消息："不支持文件格式，或者该文件是通过电子邮件发送的，但未正确解码。"

请告诉我哪里出错？

推荐答案

您需要获取内容文件：

$openfile = fopen($File, "rb");
$data = fread($openfile,  filesize( $filename ) );
fclose($openfile);
$File = $data;
