  • $ftp_server: FTP server address.

• File paths:

  • $local_file: Path to the local file to be backed up.
  • $remote_file: Path on the FTP server where the file will be uploaded.

Error Handling

The script includes basic error handling for:

• Connection to the FTP server.
• Login to the FTP server.
• File upload process.

Example

Here's an example configuration for the script:

// FTP credentials
$ftp_username = 'your_ftp_username';
$ftp_userpass = 'your_ftp_password';
$ftp_server = 'your_ftp_server_address';

// Files
$local_file = '/path/to/your/local/file';
$remote_file = '/path/on/ftp/server/file';

// Connect to FTP server
$ftp_conn = ftp_connect($ftp_server);
if (!$ftp_conn) {
    die("Couldn't connect to $ftp_server\n");
}

// Login to FTP server
$login = ftp_login($ftp_conn, $ftp_username, $ftp_userpass);
if (!$login) {
    ftp_close($ftp_conn);
    die("FTP login failed\n");
}

// Upload file
if (ftp_put($ftp_conn, $remote_file, $local_file, FTP_BINARY)) {
    echo "Successfully uploaded $local_file to $remote_file\n";
} else {
    echo "Error uploading $local_file\n";
}

// Close FTP connection
ftp_close($ftp_conn);
