What are the potential pitfalls of chaining include/require statements in a directory structure in PHP?

Chaining include/require statements in a directory structure in PHP can lead to potential issues such as file path errors, duplication of included files, and decreased code readability. To solve this, it is recommended to use an autoloader function or a framework that handles file inclusions automatically based on class names. 

// Example of using an autoloader function to include files based on class names

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