How can a PHP beginner effectively remove a sidebar from a Wordpress theme without causing issues?

To effectively remove a sidebar from a Wordpress theme without causing issues, a PHP beginner can navigate to the theme's template files and locate the file responsible for displaying the sidebar. They can then comment out or delete the code related to the sidebar in that file. Additionally, they may need to adjust the CSS styles to ensure the content fills the space previously occupied by the sidebar.

<?php
// Locate the file responsible for displaying the sidebar, such as sidebar.php or functions.php
// Comment out or delete the code related to the sidebar in that file
// Adjust CSS styles to ensure the content fills the space previously occupied by the sidebar
