我制作了一个程序来使用 php 从 gmail 下载电子邮件并保存到 html 文件。一切正常的文件，它的连接，下载邮件，下载附件，下载嵌入式邮件，它还保存到 html 文件，一切正常，但只有一些邮件像：

示例 1：

--_008_8BDE32B1FDB5C947B54F92503EC9934F015611E6glmrsvrmail1gil_ Content-Type: multipart/alternative; boundary="_000_8BDE32B1FDB5C947B54F92503EC9934F015611E6glmrsvrmail1gil_" --_000_8BDE32B1FDB5C947B54F92503EC9934F015611E6glmrsvrmail1gil_ Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: base64 RGVhciBSb3NlLA0KDQpHcmVldGluZ3MgZnJvbSBHaWxpIExhbmthbmZ1c2hp IE1hbGRpdmVzIQ0KDQpXZSBhcmUgZGVsaWdodGVkIHRvIGNvbmZpcm0geW91

示例 2： 在 Gmail 中，它以彩色和 HTML 显示，但在这里它将所有文本集中在一起，但没有 html 和颜色

我正在使用以下方式下载邮件，请它只用于一些邮件注意：我对附件没有问题..

function read_all_parts($mbox,$uid)
{
global $mime,$ret_info,$enc;
$mime = array("text","multipart","message","application","audio","image","video","other","unknow");
$enc  = array("7BIT","8BIT","BINARY","BASE64","QUOTED-PRINTABLE","OTHER","base64");
$struct = imap_fetchstructure($mbox, $uid );
$ret_info = array();


$ret_info = $this->scan($struct->parts,0);
return $ret_info;
}

$structure = imap_fetchstructure($mbox, $message_id);
$mailDivided= $mailObj->read_all_parts($mbox,$message_id);

if(count($mailDivided)!=0){
    /* ////////////////////////////////////////////////////////////////////// */
    $plainText = 1;
    foreach ($mailDivided as $key=>$parts)  {
        if($parts['pid']=='1.2' && $parts['encoding']=='QUOTED-PRINTABLE'):
            $plainText = '1.2'; # which means this is contains html text
        endif;

        if($parts['pid']=='1.2' && $parts['encoding']=='7BIT'):
            $plainText = '1.2'; # which means this is contains html text
        endif;

        if($parts['pid']=='1.2' && $parts['encoding']=='8BIT'):
            $plainText = '1.2'; # which means this is contains html text
        endif;

        if($parts['pid']=='1.1.2' && $parts['encoding']=='QUOTED-PRINTABLE'):
            $plainText = '1.1.2'; # which means this is contains html text
        endif;

        if($parts['pid']=='2' && $parts['encoding']=='QUOTED-PRINTABLE'):
            $plainText = '2'; # which means this is contains html text
        endif;
    }
    /* ////////////////////////////////////////////////////////////////////// */        
    $mymail = imap_fetchbody($mbox,$message_id,$plainText);
    if(imap_base64($mymail)){
        print "This is imap_base64 <br>";
        $mymailBody = imap_base64($mymail);
        $mymailBody =  nl2br($mymailBody);

    }else if (imap_qprint($mymail)){
        print "This is imap_qprint <br>";
        $mymailBody = imap_qprint($mymail);

    }else{
        if ($plainTex==1){
            print "This is nl2br <br>";
            $mymailBody =  nl2br($mymail);
        }else{
            print "This is quoted_printable_decode <br>";
            $mymailBody = quoted_printable_decode($mymail);
        }
    }
    /* ////////////////////////////////////////////////////////////////////// */
}else{
    print "This is encodingMailbody <br>";
    $mymail = imap_fetchbody($mbox,$message_id,'1');
    $mymailBody = $mailObj->encodingMailbody($mymail,$structure->encoding);
    $mymailBody = nl2br($mymailBody);
}

我一直在检查和尝试所有可能的事情，没有任何帮助。

会中断的电子邮件与不会中断的电子邮件有什么共同点吗？乍一看，字符集似乎可能不同。

另外，我会尝试查看电子邮件标头以查看它们的格式是否不同，因为不同的发件人对电子邮件标头的结构不同。
