PHP - IMAP：附件保存到特定的文件夾

Question

我發現這個代碼，工作差不多大，但我需要它：

1（MUST）保存附件到特定文件夾的服務器上，而不是在那裏該.php文件是。

2.（如果可能）此時代碼會生成一些零字節大小的文件。 （我可以寫的東西，檢查文件大小，然後刪除那些零大小的文件，但我想從可能的話在第一時間創建阻止它。

<?php 

    function getFileExtension($fileName){ 
     $parts=explode(".",$fileName); 
     return $parts[count($parts)-1]; 
    } 

    $imap = imap_open($server, $username, $password) or die("imap connection error"); 
    $message_count = imap_num_msg($imap); 
    for ($m = 1; $m <= $message_count; ++$m){ 

     $header = imap_header($imap, $m); 
     //print_r($header); 

     $email[$m]['from'] = $header->from[0]->mailbox.'@'.$header->from[0]->host; 
     $email[$m]['fromaddress'] = $header->from[0]->personal; 
     $email[$m]['to'] = $header->to[0]->mailbox; 
     $email[$m]['subject'] = $header->subject; 
     $email[$m]['message_id'] = $header->message_id; 
     $email[$m]['date'] = $header->udate; 

     $from = $email[$m]['fromaddress']; 
     $from_email = $email[$m]['from']; 
     $to = $email[$m]['to']; 
     $subject = $email[$m]['subject']; 

     echo $from_email . '</br>'; 
     echo $to . '</br>'; 
     echo $subject . '</br>'; 

     $structure = imap_fetchstructure($imap, $m); 

     $attachments = array(); 
     if(isset($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($imap, $m, $i+1); 
        if($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']); 
        } 
       } 
      } 
     } 

     foreach ($attachments as $key => $attachment) { 
      $name = $attachment['name']; 
      $contents = $attachment['attachment']; 
      file_put_contents($name, $contents); 
     } 

     //imap_setflag_full($imap, $i, "\\Seen"); 
     //imap_mail_move($imap, $i, 'Trash'); 
    } 

    imap_close($imap); 

    ?> 

Answer 1

你可以寫文件任何你喜歡的文件夾時，rename()功能可用於此目的

http://php.net/manual/en/function.rename.php

rename('image1.jpg', 'del/image1.jpg'); 

如果你想保持在同一個地方現有的文件，你應該使用複製

http://php.net/manual/en/function.copy.php

copy('image1.jpg', 'del/image1.jpg'); 

可以使用代碼後put_file_contents()到文件走動目錄/文件夾

編輯：在其他目錄下創建文件，而不是創建後移動它

file_put_contents('./myDir/myFile', $file); 

其中.代表項目的當前目錄。

此外，請記住file_put_contents()不創建文件夾/他們需要現有目錄或需要使用mkdir()
