删除FTP连接中的文件夹和所有文件 [英] Delete folder and all files on FTP connection

问题描述

尝试添加使用FTP删除文件夹的功能以及该文件夹中包含的所有子文件夹和文件。

我已经构建了一个递归函数来完成此操作，并且我觉得这样的逻辑是正确的，但仍然无法正常工作。

我做了一些测试，如果路径只是一个空文件夹，只是一个文件，但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，则无法删除。所以它似乎是遍历文件夹并使用函数删除的问题。

有什么想法？

  function ftpDelete（$ directory）
 {
 if（empty（$ directory））//验证目录是否被发送，否则将删除ALL文件/文件夹
返回json_encode（false）; 
 else {
 global $ conn_id; 
＃这里我们尝试删除文件/目录
 if（！（@ ftp_rmdir（$ conn_id，$ directory）|| @ftp_delete（$ conn_id，$ directory）））
 {
＃如果删除尝试失败，则获取文件列表
 $ filelist = @ftp_nlist（$ conn_id，$ directory）; 
 
＃循环遍历文件列表并递归删除列表中的文件
 foreach（$ filelist as $ file）
 ftpDelete（$ file）; 
 
＃如果文件列表为空，请删除我们通过
 ftpDelete（$ directory）的DIRECTORY; 
} 
 else 
 return json_encode（true）; 
} 
}; 
  

解决方案

确定发现我的问题。由于我没有进入我想要删除的确切目录，每个被调用的递归文件的路径都不是绝对的：

  function ftpDeleteDirectory（$ directory）
 {
 global $ conn_id; 
 if（empty（$ directory））//验证目录是否被发送，否则将删除所有文件/文件夹
返回json_encode（false）; 
 else {
＃这里我们尝试删除文件/目录
 if（！（@ ftp_rmdir（$ conn_id，$ directory）|| @ftp_delete（$ conn_id，$ directory））） 
 {
＃如果删除尝试失败，则获取文件列表
 $ filelist = @ftp_nlist（$ conn_id，$ directory）; 
＃遍历文件列表并递归删除列表中的FILE 
 foreach（$ filelist as $ file）
 {
 //返回json_encode（$ filelist）; 
 ftpDeleteDirectory（$ directory。'/'。$ file）; / ***这是我必须将绝对路径重新映射到文件的位置*** / 
} 
 
 #if文件列表为空，删除我们通过
 ftpDeleteDirectory（$ directory）的DIRECTORY; 
} 
} 
返回json_encode（true）; 
}; 
  

Trying to add the ability to delete a Folder using FTP and all subfolders and files contained within that folder.

I have built a recursive function to do so, and I feel like the logic is right, but still doesnt work.

I did some testing, I am able to delete on first run if the path is just an empty folder or just a file, but can't delete if it is a folder containing one file or a folder containing one empty subfolder. So it seems to be a problem with traversing through the folder(s) and using the function to delete.

Any ideas?

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);
    }
};

解决方案

Ok found my problem. Since I wasn't moving into the exact directory I was trying to delete, the path for each recursive file being called wasn't absolute:

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);
};
