Custom Nested Blocks in Magento

Question

PHP

I'm trying to implement childBlock in the main one in different ways. But in any case, it displays a set of some unreadable characters on the screen. What is it all about? Has anyone experienced this?

I just don't understand what's going on, any way produces such a result.

Method 1 directly in the template

$this->getLayout()->createBlock('core/template','template_name')->setTemplate('path/to/template.phtml'))->toHtml();

Method 2 in layout

<block type="module/block" name="view" template="path/to/template.phtml">
    <block type="module/block_question" name="view_question" as="question" template="path/to/subtemplate.phtml"/>
</block>

Accordingly in the template path/to/template.phtml

<?php echo $this->getChildHtml('question'); ?>

Answer 1

In general, the behavior is not clear when the time will definitely need to be picked. But the meaning is something like this, trying to treat some objects or their methods as a different data type.

Answer 2

Is caching disabled? Do the template file encodings match?
