What are some potential challenges when working with WordPress data in a separate PHP application?

One potential challenge when working with WordPress data in a separate PHP application is accessing the WordPress database tables directly. Since WordPress uses a custom database structure, querying data directly from its tables can be complex and may lead to compatibility issues in the future. A better approach is to utilize the built-in WordPress functions and APIs to retrieve the necessary data in a more secure and reliable manner. 

// Example of retrieving WordPress post data using built-in functions
require_once('wp-load.php'); // Load WordPress environment

$post_id = 1; // ID of the post to retrieve
$post = get_post($post_id);

if ($post) {
    echo 'Post Title: ' . $post->post_title;
    echo 'Post Content: ' . $post->post_content;
} else {
    echo 'Post not found.';
}
