PHP | Upload and download files via FTP server

This repository is an example of upload and download files via FTP server using PHP.

The primary purpose of an FTP server is to allow users to upload files.
Uploading and downloading files using PHP FTP functions is almost similar to doing it with an FTP client.

• FTP Upload - ftp_put()
• FTP Download - ftp_get()

Functions

The ftp_connect(ftp_server) and ftp_login(ftp_connection, ftp_username, ftp_password) functions are used to establish the connection to the provided ftp host and log in with the ftp credentials.

$ftp_conn = ftp_connect($ftp_server);
$login = ftp_login($ftp_conn, $ftp_username, $ftp_password);

After successful logon, can use the ftp_put() or ftp_get() functions.

The ftp_put() fuction transfers the local file to the remote directory on FTP server. The function returns true or false based on the upload process and the success or error message will be displayed accordingly.

The ftp_get() fuction transfers the remote file on FTP server to the local directory. The function returns true or false based on the download process and the success or error message will be displayed accordingly.

ftp_put(ftp_conn, remote_file, local_file, mode, startpos);
// OR
ftp_get(ftp_conn, local_file, remote_file, mode, startpos);

Once the file transfer is completed, the ftp stream will be closed using the ftp_close() function.

ftp_close($ftp_conn);
