Are there any best practices for securely handling FTP connections in PHP?

When handling FTP connections in PHP, it is important to ensure that the connection is secure to protect sensitive data being transferred. One best practice is to use the FTPS protocol which adds a layer of encryption to the connection. Additionally, always validate user input to prevent any potential security vulnerabilities. 

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

// Login to FTP server
if (ftp_login($ftp_conn, $ftp_user, $ftp_pass)) {
    echo 'Connected and logged in to FTP server using FTPS';
} else {
    echo 'Failed to connect or login to FTP server';
}

// Close FTP connection
ftp_close($ftp_conn);
