I have put the following code into my header.tpl file, but I believe it is failing on the getBlock('header') call. $block returns false. I had this working in Magento 1, and this is my first attempt to write the same thing in Magento 2. Any guidance would be appreciated.
{{php}}
ini_set('display_errors',1);
ini_set('display_startup_errors',1);
error_reporting(-1);
use \Magento\Framework\App\Bootstrap;
use \Magento\Store\Model\Store;
use \Magento\Store\Model\StoreManager;
include($_SERVER['DOCUMENT_ROOT']."app/bootstrap.php");
$_SERVER[StoreManager:
ARAM_RUN_CODE] = 'default';
$bootstrap = Bootstrap::create(BP, $_SERVER);
$obj = $bootstrap->getObjectManager();
/* @var Magento\Framework\App\State $state */
$state = $obj->get('Magento\Framework\App\State');
$state->setAreaCode('frontend');
/* @var \Magento\Framework\View\LayoutInterface $layout */
$layout = $obj->create("\\Magento\\Framework\\View\\LayoutInterface");
echo 'one';
/* @var \Magento\Framework\View\Element\Messages $block */
$block = $layout->getBlock('header');
echo 'two';
//echo $block->toHtml();
//var_dump($block);
echo 'three';
