How does accessing a web directory via FTP relate to the condition $datei != "." && $datei != ".."?

When accessing a web directory via FTP, it is important to exclude the "." and ".." directories to prevent accessing the parent directory or the current directory repeatedly. This condition $datei != "." && $datei != ".." ensures that only valid files and directories are processed while iterating through the directory contents. 

// Iterate through the directory contents
foreach (ftp_nlist($conn_id, ".") as $datei) {
    if ($datei != "." && $datei != "..") {
        // Process valid files and directories here
    }
}
