Entity creating with PHP?

[Zubo]

When I used manual "ORM (How to Manage Entities)" I managed to write little code for creating entity with 2 parameters:
<?
include ("bootstrap.php");

use\application\Espo\Core\ORM\Entity;
use\application\Espo\Controllers;
use\application\Espo\Services;
use\application\PDO;
use\application\Espo\Core\Utils\Config;
use\application\Espo\Core\ORM\EntityManager;

$entityManager = $this->getEntityManager();
$call1 = $entityManager->getEntity('Call');
$call1->set('name', 'Test Call');
$call1->set('status', 'Completed');
$entityManager->saveEntity($call1);
?>

I got same error every time I'm trying to process it
Fatal error: Using $this when not in object context in /var/www/admin/www/server_name/test.php

How to define "$this"? Documentation have nothing about it

Create entryPoint in application/Espo/EntryPoints

it will be available by url entryPoint=entryPointName

http://server_name/?entryPoint=Call shows me error "404 Page Not Found"

Do I need to create new file in EntryPoints folder? Also, can I find manuals to create new classes and entities programmatically?

What do I need to create and edit entities by PHP or JS code? Sorry for domb question, but I new in EspoCRM and want to learn.

I have a page "http://server_name/#Call" with button "Create Call", but I have to create new enities with GET-query

Create a file application/Espo/Modules/YOUR_MODULE/EntryPoints/CallEntryPoint.php

class CallEntryPoint extends \Espo\Core\EntryPoints\Base
{
    public function run()
    {
        $entityManager = $this->getEntityManager();
    }
}

Thanks! Now I managed to create new entites programmatically by GET-queries

But... how to create whole new "class" like "class Lead extends \Espo\Core\Entities\Person"...

Where to write field names and classes? What files I have to create?
