How can errors in include statements be effectively handled in PHP to avoid issues with namespaces?

When handling errors in include statements in PHP to avoid issues with namespaces, it is important to use the `require_once` or `include_once` functions instead of `require` or `include`. This ensures that the file is only included once, preventing conflicts with namespaces. Additionally, using the `__DIR__` constant to specify the absolute path of the file can help avoid errors related to file paths.

// Example of handling errors in include statements to avoid namespace issues
require_once __DIR__ . '/path/to/file.php';
