VK api SDK installation and connection, how to do it right?

Question

PHP

I can’t get to the bottom of it ... Today, for the first time in my life, I installed something on the site with git through the terminal ...
I decided to inquire about how the VK api SDK works, but I couldn’t even connect it))))
There is little information on the network, in the instructions not a word about it ...
In which folder should the SDK be installed? in public_html?
As I understand it, you can connect autoload.php and then functions, but will it pull up the necessary files on its own?
Thank you!

Here is a working version, the problem was that you cannot use classes that are not in the same namespace as the current script.

require_once __DIR__.'/vendor/autoload.php'; 

use \VK\Client\VKApiClient;
use \VK\OAuth\VKOAuth;
use \VK\OAuth\VKOAuthDisplay;
use \VK\OAuth\Scopes\VKOAuthUserScope;
use \VK\OAuth\VKOAuthResponseType;

$vk = new VKApiClient(VER);

$oauth = new VKOAuth(); 
$client_id = API_CLIENT_ID; 
$redirect_uri = REDIR; 
$display = VKOAuthDisplay::PAGE; 
$scope = array(VKOAuthUserScope::WALL, VKOAuthUserScope::GROUPS); 
$state = 'secret_state_code'; 

$browser_url = $oauth->getAuthorizeUrl(VKOAuthResponseType::CODE, $client_id, $redirect_uri, $display, $scope, $state);

print $browser_url;

It's time to discover the wonderful world of package managers!
1. First, install composer: https://getcomposer.org/doc/00-intro.md
2. Following the instructions ( https://github.com/VKCOM/vk-php-sdk), write in the project folder: composer require vkcom/vk-php-sdk
3. You will have composer.json, composer.lock files and a vendor folder.
3. Create index.php next to them and include the packages installed via composer:

<?php
require __DIR__ . '/vendor/autoload.php'; 

// теперь можем работать с VK API
$vk = new VK\Client\VKApiClient();
