What are the security implications of allowing FTP clients to delete directories?

Allowing FTP clients to delete directories can pose a significant security risk as it can lead to unauthorized deletion of important files or directories on the server. To mitigate this risk, it is recommended to restrict the FTP client's permissions to only allow them to delete files within directories, rather than entire directories themselves. 

// Restricting FTP client permissions to delete only files within directories
$ftp = ftp_connect('ftp.example.com');
ftp_login($ftp, 'username', 'password');

// Specify the directory path to delete files from
$directory_path = '/path/to/directory/';

// List files in the directory
$files = ftp_nlist($ftp, $directory_path);

// Loop through each file and delete them
foreach ($files as $file) {
    ftp_delete($ftp, $file);
}

ftp_close($ftp);
