Template::renderHtml()

\nn\t3::Template()->renderHtml(`$html = NULL, $vars = [], $templatePaths = [], $request = NULL`);

Render simple fluid code via standalone renderer

\nn\t3::Template()->renderHtml( '{_all->f:debug()} Test: {test}', $vars );
\nn\t3::Template()->renderHtml( ['Name: {name}', 'Test: {test}'], $vars );
\nn\t3::Template()->renderHtml( ['name'=>'{firstname} {lastname}', 'test'=>'{test}'], $vars );

Since TYPO3 12, the $request must also be passed when calling from a controller:

\nn\t3::Template()->renderHtml( 'templatename', $vars, $templatePaths, $this->request );

| @return string

	$returnArray = is_array($html);
	if (!$returnArray) $html = [$html];
