删除FTP连接上的文件夹和所有文件 - Delete folder and all files on FTP connection

尝试添加使用FTP删除文件夹以及该文件夹中包含的所有子文件夹和文件的功能。

我已经建立了一个递归函数来做这件事，我觉得逻辑是正确的，但仍然不起作用。

我做了一些测试，如果路径只是一个空文件夹或只是一个文件，我可以在第一次运行时删除，但如果它是一个包含一个文件的文件夹或包含一个空子文件夹的文件夹，则无法删除。因此，遍历文件夹并使用该函数删除似乎是一个问题。

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);
    }
};

我花了一些时间编写了我自己版本的ftp递归删除函数，这个函数应该是功能齐全的(我自己测试过)。

尝试并修改它以满足您的需求，如果它仍然不起作用，则说明有其他问题。您是否检查了要删除的文件的权限?

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);
  }
}

Ok找到我的问题了。因为我没有移动到我试图删除的确切目录，所以每个被调用的递归文件的路径不是绝对的:

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);
};

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);
    }
}

您必须检查(使用ftp_chdir)从ftp_nlist获得的每个"文件"，以检查它是否为目录:

foreach($filelist as $file)
{
    $inDir = @ftp_chdir($conn_id, $file);
    ftpDelete($file)
    if ($inDir) @ftp_cdup($conn_id);
}

这个简单的技巧将工作，因为如果ftp_chdir工作，当前的$file实际上是一个文件夹，你已经移动到它。然后递归地调用ftpDelete，让它删除该文件夹中的文件。然后，返回(ftp_cdup)继续。
