Php program for downloading the file tree from the ftp server to the Local Computer

Copy codeThe 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 );

$ _ FILE _ = $ _ FILE _. $ dir;
Echo $ _ FILE _. "<br/> ";
