1. Introduction

In this tutorial, we are going to uncover the fundamental differences between pages and posts in WordPress. Although both are essential in WordPress development, their features and uses distinctly vary.

By the end of this tutorial, you will understand:
- The core differences between pages and posts
- When and how to use pages and posts effectively

There are no prerequisites for this tutorial, but a basic understanding of WordPress would be beneficial.

2. Step-by-Step Guide

2.1 Posts

Posts are entries listed in reverse chronological order on your website. They have a publish date and are associated with categories and tags.
- Example: Consider blog articles, news updates, or informational articles.

2.2 Pages

Pages are static and timeless entries. They do not use tags or categories and are not listed by date.
- Example: 'About Us', 'Contact Us', or 'Services' pages.

Best Practices

• Use posts for dynamic content like blogs or news updates
• Use pages for static content or information that doesn't change often

3. Code Examples

3.1 Creating a Post

   'post_status'   => 'publish',
   'post_author'   => 1,
   'post_category' => array(8,39)
);

// Insert the post into the database
wp_insert_post( $my_post );
