+ }

+```
+
+If we need database or GET params, put it in constructor:
+
+In this example $_GET['test'] -> with RqGET object
+
+```php
+
+class ActIndex implements Action
+{
+ private $rqGet;

+ "Hello, World 2!<br>" .
+ '<a href="/login">login</a>' .
+ '$_GET[test]=' . htmlentities($test)
+ );
+ }
+}
+```
+
+GET request, POST request, Database, Config, Environment, Session:
+```php
+public function __construct(
+ Request $req = null,
+ AppPDO $db = null,
+ Config $config = null,
+ Env $env = null,
