Which function in Wordpress is responsible for outputting html?

Question

CMS

What function and in what file does the template output? Interested where exactly it is initiated.

Answer 1

The template is selected in the template-loader.php file , it is connected directly from wp-blog-header.php (which in turn is connected from index.php ) after parsing the main request.
Here you can see a simplified diagram of the entire loading process: “Make sense of WordPress core load” .

Answer 2

Well, as an example, the the_content and get_content functions. They are used both in individual post type templates (page.php, post.php, etc.) and in archive templates (archive.php, etc.), depending on the templates.
