   If you encounter any issues, you can always access the child theme’s functions.php file via FTP or the hosting File Manager to revert any problematic changes.
   
   

You might also be interested to know that adding PHP code to the functions.php file of a WordPress theme through a WordPress child theme is the best way to preserve your changes. Not only does it prevent your modifications from being overwritten during theme updates, but it also ensures the security and stability of your site.

A child theme in WordPress is a sub theme that inherits all the functionality, features, and style of its parent theme. Child themes are a safe way to modify a WordPress theme without actually making any changes to the parent theme’s files. When the parent theme gets updated, changes made in the child theme are preserved and applied on the updated version as well.

This is why child themes are the safest and best way to make changes to an existing theme. Rather than modifying theme files directly you can simply override them with the templates in the child theme.
