PHP program for downloading the file tree from the FTP server to the Local Computer

CopyCode The Code is as follows :/*
When ftp_nlist () is used for correspondence, two types of returned array values are available:
A: separate file names
B: The file name that contains the directory.
If you use this function, make sure to change it here.
*/
<? PHP
Function download_file ($ Dir, $ FC, $ _ file _)
{
$ Fn = ftp_nlist ($ FC, "."); // list the file names (including subdirectories) of the Directory, which are stored in the array.
$ Size = sizeof ($ FN );
$ Dir = ($ dir = "")? $ Dir :( '/'. $ DIR );
$ _ File _ = $ _ file _. $ dir;
Echo $ _ file _. "<br/> ";
For ($ I = 0; $ I <$ size; $ I ++)
{
