What are the best practices for efficiently transferring files from a local PC to a web server without causing excessive server load?

When transferring files from a local PC to a web server, it is important to use efficient methods to avoid causing excessive server load. One way to achieve this is by using FTP (File Transfer Protocol) for the file transfer process. FTP allows for secure and efficient transfer of files between a local PC and a web server without overloading the server.

// Example PHP code snippet for transferring files from a local PC to a web server using FTP

$local_file = 'local_file.txt';
$remote_file = 'remote_file.txt';

$ftp_server = 'ftp.example.com';
$ftp_user = 'username';
$ftp_pass = 'password';

// Connect to FTP server
$ftp_conn = ftp_connect($ftp_server) or die("Could not connect to $ftp_server");

// Login to FTP server
$login = ftp_login($ftp_conn, $ftp_user, $ftp_pass);

// Upload file to FTP server
if (ftp_put($ftp_conn, $remote_file, $local_file, FTP_ASCII)) {
    echo "File $local_file successfully uploaded to $ftp_server as $remote_file";
} else {
    echo "Error uploading file $local_file";
}

// Close FTP connection
ftp_close($ftp_conn);
