$url = getCurrentPage(); // store the $url in the database for this user
$current_page = getCurrentPage(); // loop through the navigation menu links and compare with $current_page if ($current_page == $link_url) { // add CSS class to highlight the link as active }Package library: getCurrentPage is not a built-in PHP function, so it is likely that it is part of a package or library. One possible library that provides getCurrentPage is the PHP HTTP library, which contains functions and classes for working with HTTP requests and responses.
