What are the potential pitfalls of using require_once in PHP for loading layouts?

Using require_once in PHP for loading layouts can lead to potential pitfalls such as file path issues, performance overhead, and difficulty in debugging. To solve this, consider using an autoloader function or a more robust framework that handles file inclusions more efficiently. 

spl_autoload_register(function($class) {
    $file = __DIR__ . '/' . str_replace('\\', '/', $class) . '.php';
    if (file_exists($file)) {
        require_once $file;
    }
});
