删除FTP连接中的文件夹和所有文件

Question

尝试添加使用FTP和该文件夹中包含的所有子文件夹和文件删除文件夹的功能。

我已经构建了一个递归函数来做到这一点，我觉得这个逻辑是正确的，但仍然无法正常工作。

我做了一些测试，我可以在第一次运行时删除，如果路径只是一个空文件夹或只是一个文件，但不能删除，如果它是包含一个文件的文件夹或包含一个空子文件夹的文件夹。所以它似乎是遍历文件夹并使用函数删除的问题。

任何想法？

function ftpDelete($directory) 
{ 
    if(empty($directory))//Validate that a directory was sent, otherwise will delete ALL files/folders 
     return json_encode(false); 
    else{ 
     global $conn_id; 
     # here we attempt to delete the file/directory 
     if(!(@ftp_rmdir($conn_id,$directory) || @ftp_delete($conn_id,$directory))) 
     { 
      # if the attempt to delete fails, get the file listing 
      $filelist = @ftp_nlist($conn_id, $directory); 

      # loop through the file list and recursively delete the FILE in the list 
      foreach($filelist as $file) 
       ftpDelete($file); 

      #if the file list is empty, delete the DIRECTORY we passed 
      ftpDelete($directory); 
     } 
     else 
      return json_encode(true); 
    } 
};

好的发现我的问题。由于我没有移动到精确的目录，我试图删除，每个递归文件的路径被称为是不是绝对的：

function ftpDeleteDirectory($directory) 
{ 
    global $conn_id; 
    if(empty($directory))//Validate that a directory was sent, otherwise will delete ALL files/folders 
     return json_encode(false); 
    else{ 
     # here we attempt to delete the file/directory 
     if(!(@ftp_rmdir($conn_id,$directory) || @ftp_delete($conn_id,$directory))) 
     { 
      # if the attempt to delete fails, get the file listing 
      $filelist = @ftp_nlist($conn_id, $directory); 
      # loop through the file list and recursively delete the FILE in the list 
      foreach($filelist as $file) 
      { 
      // return json_encode($filelist); 
       ftpDeleteDirectory($directory.'/'.$file);/***THIS IS WHERE I MUST RESEND ABSOLUTE PATH TO FILE***/ 
      } 

      #if the file list is empty, delete the DIRECTORY we passed 
      ftpDeleteDirectory($directory); 
     } 
    } 
    return json_encode(true); 
};

你必须检查（使用ftp_chdir）为每一个“文件”你ftp_nlist去检查它是否是一个目录：

foreach($filelist as $file) 
{ 
    $inDir = @ftp_chdir($conn_id, $file); 

    ftpDelete($file) 

    if ($inDir) @ftp_cdup($conn_id); 
} 

这容易招会的工作，因为如果ftp_chdir作品，目前的$file实际上是一个文件夹，你已经进入了它。然后递归调用ftpDelete，让它删除该文件夹中的文件。之后，您移回（ftp_cdup）继续。

我花了一些时间用ftp编写我自己的递归删除函数版本，这个应该是完全可用的（我自己测试过）。

试一试并修改它以适合您的需求，如果它仍然无法正常工作还有其他问题。你有没有检查你想删除的文件的权限？

function ftp_rdel ($handle, $path) { 

    if (@ftp_delete ($handle, $path) === false) { 

    if ($children = @ftp_nlist ($handle, $path)) { 
     foreach ($children as $p) 
     ftp_rdel ($handle, $p); 
    } 

    @ftp_rmdir ($handle, $path); 
    } 
}

function recursiveDelete($handle, $directory) 
{ echo $handle; 
    # here we attempt to delete the file/directory 
    if(!(@ftp_rmdir($handle, $directory) || @ftp_delete($handle, $directory))) 
    {    
     # if the attempt to delete fails, get the file listing 
     $filelist = @ftp_nlist($handle, $directory); 
     // var_dump($filelist);exit; 
     # loop through the file list and recursively delete the FILE in the list 
     foreach($filelist as $file) {    
      recursiveDelete($handle, $file);    
     } 
     recursiveDelete($handle, $directory); 
    } 
}
