请帮忙。我意识到这是基本的东西,但我很困惑为什么我的PDF是空的。我收到带有PDF附件的电子邮件,但它们是空的PDF文件,我无法弄清楚原因。我在这里看了其他类似的问题,但没有发现它们有用。我不希望使用框架或依赖项。谢谢您的帮助。我希望在15分钟内完成这项工作,但这个错误让我反感。

$dir = "scanned_files";

function is_dir_empty($dir) {
    if(!is_readable($dir)){
        return NULL;
    }
    $handle = opendir($dir);
    while(false !== ($entry = readdir($handle))){
        if ($entry != "." && $entry != "..") {
            return FALSE;
        }
    }
    return TRUE;
}

if (is_dir_empty($dir)) {
    echo "the folder is empty"; 
}else{
    $files = array_diff(scandir($dir), array('.', '..', '.DS_Store'));

    foreach($files as $filename){
        $content = file_get_contents($dir . "/" . $filename);
        $content = chunk_split(base64_encode($content));
        $email = "someone@somewhere.com";

        $subject = "Scanned document from the road!";

        $separator = md5(time());

        $headers = "From: someone@somewhere.com" . "\r\n";
        $headers .= "MIME-Version: 1.0" . "\r\n";
        $headers .= "Content-type: multipart/mixed; boundary=\"" . $separator . "\"" . "\r\n";
        $headers .= "Content-Transfer-Encoding: 7bit" . "\r\n";

        $msg = "--" . $separator . "\r\n";
        $msg .= "Content-Type: text/plain; charset=\"iso-8859-1\"" . "\r\n";
        $msg .= "Content-Transfer-Encoding: 8bit" . "\r\n";
        $msg .= "Your file has arrived." . "\r\n";

        $msg .= "--" . $separator . "\r\n";
        $msg .= "Content-Type: application/octet-stream; name=\"" . $filename . "\"" . "\r\n";
        $msg .= "Content-Transfer-Encoding: base64" . "\r\n";
        $msg .= "Content-Disposition: attachment" . "\r\n";
        $msg .= $content . "\r\n";
        $msg .= "--" . $separator . "--";

        mail($email, $subject, $msg, $headers);
        echo PHP_EOL . "Mail sent. Filename: " . $filename . PHP_EOL;
    }
}

使用multi-part/mixed内容类型时,每个部分必须有一个空白行,将标题与正文分开。

  

每个部分以封装边界开头,然后包含一个   正文部分由标题区域,空行和正文区域组成。

W3 Documentation

在您的代码中,生成的标题和消息之间没有任何空行。

要解决此问题,请在以下行中使用\r\n\r\n代替\r\n

$headers .= "Content-Transfer-Encoding: 7bit" . "\r\n\r\n";
$msg .= "Content-Disposition: attachment" . "\r\n\r\n";

然后你的附件就会正确出来。
