Adding PHP to WordPress: How to Add Code into Any Post or Page

Here is the article. 

Looking to know how to run PHP code on a WordPress post or page? You’ve come to the right place. Here, we will uncover how to add PHP to a WordPress page or post so you can improve their functionality.

Reasons to Add PHP Code to WordPress Post or Page

By default, WordPress doesn’t allow you to run PHP code in posts or pages. The recommended way to add PHP functions is to modify the child theme or create custom page templates.

Despite so, there are occasions where you might want to add specific PHP functions to an individual post or page. In these cases, you can override the rule using WordPress code widget plugins.

The following tutorial will guide you through the process of using the Insert PHP Code Snippet plugin to add PHP code directly to a WordPress post or page.
