使用IMAP在PHP中下載附件到IMAP目錄，隨機作品

Question

我發現在線PHP代碼使用IMAP從這裏下載附件到目錄。 http://www.nerdydork.com/download-pop3imap-email-attachments-with-php.html

我修改了它稍微改變

 $structure = imap_fetchstructure($mbox, $jk); 
     $parts = ($structure->parts); 

到

 $structure = imap_fetchstructure($mbox, $jk); 
     $parts = ($structure); 

得到它才能正常運行，否則我得到stdClass的怎麼沒有定義的屬性稱爲$部分錯誤。這樣做，我可以下載所有的附件。我最近再次測試過，但沒有奏效。那麼，它沒有工作6次，第7次工作，然後從那時起一直沒有工作。我認爲這與我搞砸零件處理有關，因爲count（$ parts）每條消息都會返回1，所以它沒有找到我認爲的任何附件。

由於它在一點沒有問題下載附件，我覺得這個地區的事情已經搞砸了。在這個代碼塊之前是一個for循環，通過框中的每條消息，並且在循環之後，每個imap結構只經過$ parts。感謝您的任何幫助，您可以提供。我看着php.net上的imap_fetchstructure頁面，無法弄清楚我做錯了什麼。

編輯：我只是在輸入我的問題後再次檢查文件夾，它全部彈出。我覺得我瘋了。自從我開始輸入這些內容之前幾分鐘，我就沒有運行這些代碼，對我而言，觸發這個過程需要很長時間纔是有意義的。我在郵箱中有800條消息，但是我想，因爲它在PHP的最後打印了我的聲明，表明所有文件創建工作都已完成。

看看這個代碼：

  $structure = imap_fetchstructure($mailbox, $index); 

     $attachments = array(); 
     if(isset($structure->parts) && count($structure->parts)) { 
     for($i = 0; $i < count($structure->parts); $i++) { 
      $attachments[$i] = array(
       'is_attachment' => false, 
       'filename' => '', 
       'name' => '', 
       'attachment' => ''); 

      if($structure->parts[$i]->ifdparameters) { 
      foreach($structure->parts[$i]->dparameters as $object) { 
       if(strtolower($object->attribute) == 'filename') { 
       $attachments[$i]['is_attachment'] = true; 
       $attachments[$i]['filename'] = $object->value; 
       } 
      } 
      } 

      if($structure->parts[$i]->ifparameters) { 
      foreach($structure->parts[$i]->parameters as $object) { 
       if(strtolower($object->attribute) == 'name') { 
       $attachments[$i]['is_attachment'] = true; 
       $attachments[$i]['name'] = $object->value; 
       } 
      } 
      } 

      if($attachments[$i]['is_attachment']) { 
      $attachments[$i]['attachment'] = imap_fetchbody($connection, $message_number, $i+1); 
      if($structure->parts[$i]->encoding == 3) { // 3 = BASE64 
       $attachments[$i]['attachment'] = base64_decode($attachments[$i]['attachment']); 
      } 
      elseif($structure->parts[$i]->encoding == 4) { // 4 = QUOTED-PRINTABLE 
       $attachments[$i]['attachment'] = quoted_printable_decode($attachments[$i]['attachment']); 
      } 
      }    
     } // for($i = 0; $i < count($structure->parts); $i++) 
     } // if(isset($structure->parts) && count($structure->parts))

這是完美的工作答案，試試這個。

本示例運行正常，並且沒有問題下載所有附件。

<?php

/* connect to gmail with your credentials */ 
$hostname = '{imap.gmail.com:993/imap/ssl}INBOX'; 
$username = 'YOUR_USERNAME';

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

$emails = imap_search($inbox, 'FROM "abc@gmail.com"'); 

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

    $count = 1; 

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

    /* for every email... */
