问题描述
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.
Trying to add the ability to delete a Folder using FTP and all subfolders and files contained within that folder.
我为此构建了一个递归函数,感觉逻辑是对的,但还是不行.
I have built a recursive function to do so, and I feel like the logic is right, but still doesnt work.
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,遍历文件夹并使用删除功能似乎是一个问题.
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.
有什么想法吗?
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($directory);
}
else
return json_encode(true);
}
};
推荐答案
好的,找到了我的问题.由于我没有移动到我试图删除的确切目录,因此每个被调用的递归文件的路径都不是绝对的:
Ok found my problem. Since I wasn't moving into the exact directory I was trying to delete, the path for each recursive file being called wasn't absolute:
function ftpDeleteDirectory($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);
};
