What are some common pitfalls when including PHP files within other PHP files?

One common pitfall when including PHP files within other PHP files is using relative paths that may not work as expected when the including file is in a different directory. To solve this issue, it's recommended to use absolute paths or define a base path constant in your main file and use it when including other files. 

// Define a base path constant in your main file
define('BASE_PATH', __DIR__);

// Include other files using the base path constant
include BASE_PATH . '/path/to/your/file.php';
