In the provided PHP code snippet, what improvements can be suggested to enhance the functionality and usability of the breadcrumb navigation system?

Issue: The current breadcrumb navigation system in the PHP code snippet does not dynamically generate the breadcrumb links based on the current page. To enhance functionality and usability, we can modify the code to automatically generate breadcrumb links based on the current page's hierarchy. 

// Improved breadcrumb navigation system
function generateBreadcrumb($path) {
    $breadcrumbs = explode('/', $path);
    $breadcrumbPath = '';
    $breadcrumb = '<a href="/">Home</a>';

    foreach ($breadcrumbs as $crumb) {
        $breadcrumbPath .= '/' . $crumb;
        $breadcrumb .= ' / <a href="' . $breadcrumbPath . '">' . ucfirst($crumb) . '</a>';
    }

    echo $breadcrumb;
}

// Usage
$currentPath = $_SERVER['REQUEST_URI'];
generateBreadcrumb($currentPath);
