Can you explain the process of parsing a template within another template using IT[X] or KTemplate in PHP?

To parse a template within another template using IT[X] or KTemplate in PHP, you can first load the outer template using the IT[X] or KTemplate library, then use the `parse` method to parse the inner template within the outer template. This allows you to nest templates and render them together seamlessly.

// Load the outer template
$outerTemplate = new KTemplate('path/to/outer_template.tpl');

// Load the inner template
$innerTemplate = new KTemplate('path/to/inner_template.tpl');

// Parse the inner template within the outer template
$outerTemplate->set('inner_template_content', $innerTemplate->parse());

// Render the final template
echo $outerTemplate->parse();
