How can PHP code be modified to handle FTP connections through a proxy server effectively?

When handling FTP connections through a proxy server in PHP, you can modify the code to set the proxy settings using the `ftp_set_option()` function. This function allows you to specify the proxy host, port, username, and password before establishing the FTP connection. 

// Set proxy settings
ftp_set_option($ftp_conn, FTP_USEPASVADDRESS, false);
ftp_set_option($ftp_conn, FTP_USEEPSV, false);
ftp_set_option($ftp_conn, FTP_PROXY_HOST, 'proxy_host');
ftp_set_option($ftp_conn, FTP_PROXY_PORT, 'proxy_port');
ftp_set_option($ftp_conn, FTP_PROXY_USER, 'proxy_username');
ftp_set_option($ftp_conn, FTP_PROXY_PASS, 'proxy_password');

// Connect to FTP server using proxy
$ftp_conn = ftp_connect('ftp_server');

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

// Perform FTP operations
// ...

// Close FTP connection
ftp_close($ftp_conn);
