How can the use of an autoloader impact the resolution of namespace conflicts in PHP projects?

When working on PHP projects with multiple libraries or dependencies, namespace conflicts can arise if two classes share the same name. This can lead to fatal errors and make the code difficult to maintain. One way to resolve namespace conflicts is by using an autoloader, which dynamically loads classes only when they are needed, preventing conflicts by ensuring that each class is uniquely identified.

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