Introduction

The aim of our project ‘ServerZilla’ is to encourage transfer files between remote host and FTP server. And this project manages files in both remote host and FTP server. Currently, remote administrator uses TFTP (Trivial File Transferring Protocol) to connect remote host to FTP server. To execute TFTP, the administrator needs to spawn a shell using back connect or SSH (secured shell ).This application is based on Command Line Interface (CLI) and has several commands to encourage transfer files between remote host and FTP server which is very difficult for a normal user. Hence by doing this project, reduce this problem. This project uses a web interface which will be user friendly.

Objectives

Enable the administrator to connect the web server with FTP server.
Provide impressive and user-friendly interface.
Save time of administrator.
Transfer files between web server and FTP server.
Enable administrator to browse the files in web server and FTP server.
Enable administrator to manage the files in web server and FTP server.

Using the Code

The project used technologies like:

PHP
JavaScript
CSS3
jQuery
bootstrap
bootbox, etc

Let's start with FTP functions used in the program.

To connect to FTP server, the function ftp_connection() is used. The syntax of ftp_connect() is:

$conn = ftp_connect("hostname");

The variable $conn is the handler to connection to the FTP server. Later, it is used as reference to the connection.

The next function is to login to FTP server. The function ftp_login() is used to login to FTP server. The syntax is:

$login = ftp_login($conn, $usr, $pass);

The $usr is variable in which we have stored the username of user and $pass is the variable in which we have stored password of user.

To change the current working directory of FTP server, the function ftp_chdir() is used. The syntax is:

ftp_chdir($conn, $fpath);

The next function of FTP client is upload file to FTP server. To upload files to FTP server, the function ftp_put() is used. The syntax is:

ftp_put($conn, $rFile, $lFile, FTP_BINARY);

The variable $rFile stores the name of remote file, $lFile stores the name of local file and FTP_BINAY is the mode of operation.

The next operation of FTP client is download file. To download files to web server, the function ftp_get() is used. The syntax is:

ftp_get($conn, $lFile, $rFile, FTP_BINARY);

The variable $lFile stores the name of local file, $rFile stores the name of remote file and FTP_BINARY is the mode of operation.

The renaming of files is another function of FTP client. To rename a file on FTP host, the function ftp_rename() is used. The syntax is:

ftp_rename($conn, $oldname, $newname);

I hope you understand what the variables are used for.

The deletion of file is another function of FTP client. To delete files, the function ftp_delete() is used. The syntax is:

ftp_delete($conn, $file);

Deleting directory is the hard part because to delete a directory, the directory must be empty. So we use a recursive function to delete directory. The function code is:

            function deleteFDir($conn, $path)
            {
                $list = getfiles(ftp_pwd($conn).'/'.$path);
                foreach($list as $item)
                {
                    if($item['type']=='Directory')
                    {
                        deleteFDir($conn, $path.'/'.$item['name']);
                    }
                    else {
                        ftp_delete($conn, $path.'/'.$item['name']);
                    }
                }
                if(ftp_rmdir($conn, $path))
                {
                    return true;
                }
                else {
                    return false;
                }
            }

To create a new directory in FTP server, the function ftp_mkdir() is used. The syntax is:
