            // Get the content of the API request
            $ip_info = @file_get_contents($url);

            if ($ip_info) {
                $ip_info_data = json_decode($ip_info, true);

                // Display IP address details
                echo "<div class='result'>";
                echo "<p><strong>IP Address:</strong> " . $ip_address . "</p>";
                echo "<p><strong>Country:</strong> " . $ip_info_data['country'] . "</p>";
                echo "<p><strong>Region:</strong> " . $ip_info_data['region'] . "</p>";
                echo "<p><strong>City:</strong> " . $ip_info_data['city'] . "</p>";

            }
        }
        ?>
    </div>

    <?php
