How can including <head> and header/footer files in PHP be managed when dividing a website into subdirectories?

When dividing a website into subdirectories in PHP, managing the inclusion of <head> and header/footer files can be achieved by using relative paths. By using "../" to navigate up a directory level, you can include the necessary files from the root directory regardless of the current subdirectory location. This ensures that the header/footer files are included correctly across different pages and subdirectories. 

&lt;?php
include &#039;../header.php&#039;; // Include header file using relative path
?&gt;

&lt;!-- Content of the page --&gt;

&lt;?php
include &#039;../footer.php&#039;; // Include footer file using relative path
?&gt;
