What security considerations should be taken into account when handling FTP connections in PHP?

When handling FTP connections in PHP, it is important to ensure that sensitive information such as usernames and passwords are not exposed in plain text. One way to address this security concern is to use FTPS (FTP over SSL/TLS) to encrypt the connection and protect the data being transferred. 

// Connect to FTP server using FTPS
$ftp_server = 'ftp.example.com';
$ftp_user = 'username';
$ftp_pass = 'password';

$conn_id = ftp_ssl_connect($ftp_server);
$login_result = ftp_login($conn_id, $ftp_user, $ftp_pass);

if (!$conn_id || !$login_result) {
    die('FTP connection failed.');
} else {
    echo 'Connected to FTP server.';
}

// Perform FTP operations here

// Close the FTP connection
ftp_close($conn_id);
