What are the reasons for needing to know the page the user is on when comparing it with a link?

When comparing the current page with a link in PHP, it is important to know the current page the user is on in order to properly highlight or style the link if it corresponds to the current page. This can help improve user experience by providing visual cues as to which page they are currently on. One way to achieve this is by using the $_SERVER['REQUEST_URI'] variable in PHP to get the current page URL and then comparing it with the link URL. 

$current_page = $_SERVER['REQUEST_URI'];
$link_url = "/some/link/url";

if ($current_page == $link_url) {
    echo '<a href="' . $link_url . '" class="current-page">Link Text</a>';
} else {
    echo '<a href="' . $link_url . '">Link Text</a>';
}
