现在终于到了我们的第三个文件，include.php 它为程序建立起一个用户界面。
"include.php" 包含三个表单，一些PHP代码获取当前的目录列表并将它们存入三个变量
$files (包括当前目录下的文件）,
$file_sizes (相应的文件大小),
and $dirs (包含子目录名)
第一个表单使用$dirs 产生一个下拉式目录列表，对应于“action=CWD”。
第二个表单使用$files$file_sizes创建一个可用的文件列表，每一个文件使用一个checkbox。这个表单的action对应于"action=Delete" and "action=Download"
第三个表单用来上传一个文件到FTP站点，如下：
--------------------------------------------------------------------------------
<form enctype="multipart/form-data" action=actions.php4 method=post>
...
<input type=file name=upfile>
...
</form>
--------------------------------------------------------------------------------
当PHP以这种方式接收到一个文件名，一些变量就产生了，这些变量指定文件的大小，一个临时的文件名以及文件的类型，最初的文件名存在$upfile_name，一旦上传后文件名便存入$upfile中（这个变量是由PHP自己创建的）
通过这些信息，我们就可以创建以下的语句了：
--------------------------------------------------------------------------------
ftp_put($result, $upfile_name, $upfile, FTP_BINARY);
--------------------------------------------------------------------------------
以下是代码列表：
