【问题描述】：

连接到我的电子邮件帐户以阅读邮件并通过 php 代码将附件下载到服务器

到目前为止，我已经使用了third code that appears here 确实 [来自 GuRu] 如果它可以使会员更容易，这里是代码的副本。

    <?php

set_time_limit(3000); 

/* connect to gmail with your credentials */
$hostname = 'imap.gmail.com:993/imap/sslINBOX';
$username = 'YOUR_USERNAME'; 
$password = 'YOUR_PASSWORD';

/* try to connect */
$inbox = imap_open($hostname,$username,$password) or die('Cannot connect 
to Gmail: ' . imap_last_error());

$emails = imap_search($inbox, 'FROM "[e-mail]"');

/* if any emails found, iterate through each email */
if($emails) 

    $count = 1;

    /* put the newest emails on top */
    rsort($emails);

    /* for every email... */
    foreach($emails as $email_number) 
    

    /* get information specific to this email */
    $overview = imap_fetch_overview($inbox,$email_number,0);

    $message = imap_fetchbody($inbox,$email_number,2);

    /* get mail structure */
    $structure = imap_fetchstructure($inbox, $email_number);

    $attachments = array();

    /* if any attachments found... */
    if(isset($structure->parts) && count($structure->parts))

                    if(strtolower($object->attribute) == 'name') 
                    
                        $attachments[$i]['is_attachment'] = true;
                        $attachments[$i]['name'] = $object->value;
                    
                
            

            if($attachments[$i]['is_attachment']) 
            
                $attachments[$i]['attachment'] = imap_fetchbody($inbox,

                    /* 3 = BASE64 encoding */
                    if($structure->parts[$i]->encoding == 3) 
                     
                        $attachments[$i]['attachment'] = 
base64_decode($attachments[$i]['attachment']);
                    
                    /* 4 = QUOTED-PRINTABLE encoding */
                    elseif($structure->parts[$i]->encoding == 4)

    /* iterate through each attachment and save it */
    foreach($attachments as $attachment)
    
        if($attachment['is_attachment'] == 1)
        
            $filename = $attachment['name'];
            if(empty($filename)) $filename = $attachment['filename'];

            if(empty($filename)) $filename = time() . ".dat";
            $folder = "attachment";
            if(!is_dir($folder))
            
                 mkdir($folder);
            
            $fp = fopen("./". $folder ."/". $email_number . "-" . 
$filename, "w+");
                fwrite($fp, $attachment['attachment']);
                fclose($fp);
            
        
    
 

/* close the connection */
imap_close($inbox);

echo "all attachment Downloaded";

?>

英文或数字名称的附件非常棒！ 但如果名称是希伯来语，则文件名的编码如下： 1424 - =？ UTF-8？乙？ 15TXntec16bXlCDXoteR15XXqCDXkNek15zXkdeQ15XXnSDXkg ==？ = =？ UTF-8？乙？ 150g16jXkSDXkteV15DXnNee158yICgxKS5qcGc =？ =

我一直在一天中的任何时间搜索几天，我尝试了很多代码。同时， 我不知道该怎么办！

（也许我只是没有将修复程序放在正确的位置？无论如何，目前我真的很绝望，如果有人可以提供帮助，我很乐意提供任何实用的解决方案。）

以下是一些尝试：

Sending an email with attachment displays in encoded format PHP 我认为这正是我的问题的标题。但是我无法以可以合并到我的代码或此处提供的代码中的方式找出答案

setting encoding for attachment in phpmailer 虽然它并不完全相关，但它可能会有所帮助。反正我是来不及了

Reload this Page PHP: Send email with attachment and UTF8 in filenames

Base 64 Attachment in PHP Mail() not working 虽然它确实提供了代码，但它是用于发送和接收电子邮件的代码。这对我有什么帮助？

Sending MIME-encoded email attachments with utf-8 filenames

同样的问题

PHP - Convert string to unicode 我无法将其集成到代码中

How to read the Content Type header and convert into utf-8 while Gmail IMAP has utf8 and Outlook has ISO-8859-7? 没有帮助我

这只是一部分... 我会很感激任何想法 谢谢！！

【参考方案1】：

经过大量搜索和尝试，这行挽救了局面：是jlh先生带来的on this page：

iconv_mime_decode($str, ICONV_MIME_DECODE_CONTINUE_ON_ERROR, 'UTF-8')

我把它放在这里：

                $filename = $attachment['name'];
                    $filename = iconv_mime_decode($filename, ICONV_MIME_DECODE_CONTINUE_ON_ERROR, 'UTF-8');

            if(empty($filename)) $filename = $attachment['filename'];

希望对做更多好事有所帮助
