What are some best practices for organizing files in a PHP project to avoid inclusion issues?

When organizing files in a PHP project, it is important to follow a consistent structure to avoid inclusion issues. One common approach is to use namespaces to organize classes and functions logically. Additionally, using an autoloader can help automatically load classes when they are needed, reducing the risk of including files multiple times. 

// Autoloader function to load classes automatically
spl_autoload_register(function ($class) {
    // Convert class name to file path
    $file = __DIR__ . '/' . str_replace('\\', '/', $class) . '.php';
    
    // Check if file exists and include it
    if (file_exists($file)) {
        include $file;
    }
});
