Execution Sample
Wordpress
<?php
// index.php
get_header();
if (have_posts()) {
  while (have_posts()) {
    the_post();
    the_content();
  }
}
get_footer();
This code loads the header, loops through posts to show content, then loads the footer in a WordPress theme.

Key Moments - 3 Insights
Why do we need to understand header.php and footer.php?
Because these files control the top and bottom parts of every page, knowing them helps you change site layout easily, as shown in steps 1 and 6 of the execution_table.
What happens if have_posts() returns false?
The loop to show posts does not run, so no post content appears. This is shown at step 5 where the loop ends because no more posts exist.
How does functions.php affect the site?
It adds features like menus or scripts that make the site interactive, as seen in step 8 where functions.php runs after content and styles load.

Full Transcript
When WordPress builds a website, it loads theme files in order. First, header.php creates the top part of the page. Then index.php checks if there are posts and loops through them to show content. After all posts show, footer.php adds the bottom part. Style.css styles the site with colors and layout. Functions.php adds extra features like menus. Knowing how these files work helps you change your site's look and behavior easily. For example, if you want to change the header, you edit header.php. If you want to add a new feature, you use functions.php. This step-by-step loading is shown in the execution table, helping you see what each file does and when.
