What are the best practices for handling file operations on remote servers in PHP, especially when dealing with FTP?

When handling file operations on remote servers in PHP, especially when dealing with FTP, it is important to ensure secure and reliable connections, handle errors gracefully, and properly manage file permissions. One common practice is to use PHP's built-in FTP functions to establish a connection, upload/download files, and close the connection when finished. 

// Connect to FTP server
$ftp_server = 'ftp.example.com';
$ftp_user = 'username';
$ftp_pass = 'password';
$ftp_connection = ftp_connect($ftp_server);
$login = ftp_login($ftp_connection, $ftp_user, $ftp_pass);

if (!$ftp_connection || !$login) {
    die('FTP connection failed');
}

// Upload file
$file_path = 'local_file.txt';
$remote_file = 'remote_file.txt';
if (ftp_put($ftp_connection, $remote_file, $file_path, FTP_BINARY)) {
    echo 'File uploaded successfully';
} else {
    echo 'Failed to upload file';
}

// Close FTP connection
ftp_close($ftp_connection);
