Are there any security considerations to keep in mind when using FTP functions in PHP?

When using FTP functions in PHP, it is important to consider security implications such as transmitting sensitive data in plain text. To mitigate this risk, it is recommended to use FTPS (FTP over SSL) for secure data transmission. This can be achieved by connecting to the FTP server using an SSL/TLS connection. 

// Connect to FTP server using FTPS
$ftp_server = 'ftp.example.com';
$ftp_username = 'username';
$ftp_password = 'password';
$ftp_connection = ftp_ssl_connect($ftp_server);

// Login to FTP server
ftp_login($ftp_connection, $ftp_username, $ftp_password);

// Perform FTP operations securely
// Example: ftp_put($ftp_connection, 'remote_file.txt', 'local_file.txt', FTP_BINARY);

// Close FTP connection
ftp_close($ftp_connection);
