Magento 2 setTemplate and add content to phtml template

Question

How to add bare HTML to a block e.g:

$block = $result->getLayout()->getBlock('category.description');
$block->setTemplate('Vendor_Module::myTemplate/blank.phtml')
->toHtml('<p>My Content</p>');

Is there a way to dynamically add content to a block perhaps without use of templates or any other way appreciate?

Answer 1

You should try this

 echo $this->getLayout()->createBlock("Vendor\Module\Block\Myblock")- 
>setTemplate("My_Module::history-suite.phtml")->toHtml();

Answer 2

I've found a solution pretty simple.

$block = $result->getLayout()->setData(['test'=> 'Content here'])->getBlock('category.description');
$block->setTemplate('Vendor_Module::myTemplate/blank.phtml')
->toHtml();

Then my blank.phtml:

<?php print_r($this->getData()) ?>

It prints: Array ( [test] => Content here [module_name] => Magento_Catalog )
