+To Integrate with menu just call this function
+
+```php
+**
+ * Register for global menu
+ * @param string name Name of the menu
+ * @param bool admin true if for admin and false for customer
+ * @param string function function to run after menu clicks
+ * @param string position position of menu, use AFTER_ for root menu |
+ * Admin/Sales menu: AFTER_DASHBOARD, CUSTOMERS, PREPAID, SERVICES, REPORTS, VOUCHER, AFTER_ORDER, NETWORK, SETTINGS, AFTER_PAYMENTGATEWAY
+ * | Customer menu: AFTER_DASHBOARD, ORDER, HISTORY, ACCOUNTS
+ * @param string icon from ion icon, ion-person, only for AFTER_
+ * @param string label for showing label or number of notification or update
+ * @param string color Label color
+ * @param string auth authorization ['SuperAdmin', 'Admin', 'Report', 'Agent', 'Sales'] will only show in this user, empty array for all users
+ */
+function register_menu($name, $admin, $function, $position, $icon = '', $label = '', $color = 'success', $auth = []);
+
+// Example
+register_menu("Port Tester", true, "port_tester", 'SETTINGS', '');
+```
+
+then you need to create function with name `port_tester`
+
+```php
+function port_tester()
+{
+    global $ui;
+    _admin();
+    $ui->assign('_title', 'Port Tester');
+    $ui->assign('_system_menu', 'settings');
+
+    $port = _post('port', 8278);
+    $ui->assign('port', $port);
+
+    if (isset($_POST['port']) && !empty($_POST['port'])) {
+        ini_set('default_socket_timeout', 10);
+        $result = 'portquiz.net IP: <b>' . gethostbyname('portquiz.net') . "</b>\n";
+        $result .= Http::getData('http://portquiz.net:' . $port, ['User-Agent: wget']);
+        if (strpos($result, 'successful')) {
+            $ui->assign('result', str_replace('Port test successful', "Testing Port <b>$port</b> test successful", $result));
+        } else {
+            $ui->assign('result', "Testing Port <b>$port</b> test Failed");
+        }
+    }
+
+    $admin = Admin::_info();
+    $ui->assign('_admin', $admin);
+    $ui->display('port_tester.tpl');
+}
+```
+
+for `.tpl` file, you need to put to folder `ui`
