How can one troubleshoot include path errors in PHP scripts?

To troubleshoot include path errors in PHP scripts, you can check the file paths in the include statements to ensure they are correct. You can also use the `__DIR__` or `dirname(__FILE__)` magic constants to specify the full path to the included files. Additionally, you can use `set_include_path()` to set the include path dynamically.

// Example of using __DIR__ to specify the full path to the included file
include __DIR__ . '/path/to/file.php';
