Print a view inside a block In Drupal 7, I use the following code to print more than one view inside a block.

&lt;?php print views_embed_view('view_name', 'display_name'); ?&gt;


In Drupal 8, it doesn't work and it returns Array. Although the documentation for views_embed_view() says it's the same as in Drupal 7, it doesn't work in blocks using the PHP filter module.
I can't help with the PHP filter and I don't think it is safe to use it in D8 by looking at the project's page. 

There are better solutions. You could for example add a Views Reference Field to the block type or use Twig Tweak in a template. You can also try to embed the View in the WYSIWYG text area, which is a bit more work to set up, but then should give you all options you have now in D7. See Views entity embed.
