And now we finally got to our third file, include.php it creates a user interface for the program.
"Include.php" contains three forms, some PHP code gets the current directory list and deposits them into three variables
$files (including files in the current directory),
$file _sizes (the corresponding file size),
and $dirs (contains subdirectory names)
The first form uses $dirs to produce a drop-down list of directories, corresponding to "ACTION=CWD".
The second form uses $files $file _sizes to create a list of available files, each using a checkbox. The action of this form corresponds to "Action=delete" and "Action=download"
The third form is used to upload a file to the FTP site, as follows:
--------------------------------------------------------------------------------
<form enctype= "Multipart/form-data" Action=actions.php4 method=post>
...
<input Type=file name=upfile>
...
</form>
--------------------------------------------------------------------------------
When PHP receives a filename in this way, some variables are generated, these variables specify the size of the file, a temporary file name and the type of file, the original filename exists $upfile_name, once uploaded, the filename is deposited into $ Upfile (this variable is created by PHP itself)
With this information, we can create the following statement:
--------------------------------------------------------------------------------
Ftp_put ($result, $upfile _name, $upfile, ftp_binary);
--------------------------------------------------------------------------------
The following is a list of codes:
