How can one troubleshoot issues with FTP connections in PHP?

To troubleshoot issues with FTP connections in PHP, you can check if the FTP extension is enabled in your PHP configuration, verify the FTP server credentials, make sure the FTP server is running and accessible, and check for any firewall or network issues that may be blocking the connection. 

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

// Verify FTP server credentials
$ftp_server = 'ftp.example.com';
$ftp_username = 'username';
$ftp_password = 'password';

// Connect to FTP server
$ftp_conn = ftp_connect($ftp_server);
if (!$ftp_conn) {
    die('Unable to connect to FTP server.');
}

// Login to FTP server
if (!ftp_login($ftp_conn, $ftp_username, $ftp_password)) {
    die('Login failed.');
}

// Perform FTP operations here

// Close FTP connection
ftp_close($ftp_conn);
