Magento 1 Way :-

https://inchoo.net/magento/injecting-variables-into-a-magento-cms-static-block/

I need the same in Magento 2, how can I achieve? it's urgent.

Here is my afford:-

<?php

namespace Test\Clientform\Controller\Show;

use Magento\Framework\App\ObjectManager;

class Index extends \Magento\Framework\App\Action\Action
{
    protected $_filterProvider;
    protected $_storeManager;
    protected $_blockFactory;
    protected $_filterFactory;

    public function __construct(
        \Magento\Framework\App\Action\Context $context,
        \Magento\Cms\Model\Template\FilterProvider $filterProvider,
        \Magento\Store\Model\StoreManagerInterface $storeManager,
        \Magento\Cms\Model\BlockFactory $blockFactory,
        \Magento\Framework\Filter\Template $filterFactory,
        array $data = []
    )
    {
        parent::__construct($context, $data);
        $this->_filterProvider = $filterProvider;
        $this->_storeManager = $storeManager;
        $this->_blockFactory = $blockFactory;
        $this->_filterFactory = $filterFactory;
    }

    public function execute()
    {


        $blockId = 'client_intake_form';
        $html = '';
        if ($blockId) {
            $storeId = $this->_storeManager->getStore()->getId();
            /** @var \Magento\Cms\Model\Block $block */
            $block = $this->_blockFactory->create();
            $block->setStoreId($storeId)->load($blockId);

            $array['full_name'] = 'test';

             $this->_filterFactory->setVariables($array);
             // exit;
             //exit;
                $html = $this->_filterProvider->getBlockFilter()->setStoreId($storeId)->filter($block->getContent());
        }
        echo   $html;

        // $resultPage = $this->_resultPageFactory->create();
        // return $resultPage;
    }



}

?>

When I'm hitting controller:-

http://127.0.0.1/Magento2/test/show/index

still not able to set value.

you can check here:-

To set value I've used \Magento\Framework\Filter\Template $filterFactory,

& calling setVariables() method.

When I'm setting values directly in the core class:-

\Magento\Framework\Filter\Template $filterFactory

e.g-

public function setVariables(array $variables)
    {
        $variables['full_name'] = 'test'; // added this line staticaly
        foreach ($variables as $name => $value) {
            $this->templateVars[$name] = $value;
        }
        return $this;
    }

Then value gets set, you can check here:-

so please let me know why I'm not able to set value from the controller.
