What are the potential pitfalls of mixing PHP and Wordpress functions in a code snippet?

Mixing PHP and WordPress functions in a code snippet can lead to compatibility issues and unexpected behavior. To avoid potential pitfalls, it's best to stick to using either PHP or WordPress functions exclusively in a code snippet. If you need to use both, consider separating them into distinct sections or functions to maintain clarity and prevent conflicts.

// Example of separating PHP and WordPress functions into distinct sections

// PHP code section
$variable = 10;

// WordPress code section
$post_id = get_the_ID();
$title = get_the_title($post_id);
