Are there any specific server configurations or settings that need to be adjusted to enable the use of FTP functions in PHP?

To enable FTP functions in PHP, you may need to ensure that the PHP configuration has the "ftp" extension enabled. Additionally, you may need to check that the server's firewall settings allow FTP connections. 

// Check if FTP extension is enabled
if (!extension_loaded('ftp')) {
    die('FTP extension is not enabled.');
}

// Check firewall settings to allow FTP connections
// Make sure port 21 is open for FTP
