How can PHP developers ensure that links within their website, such as those leading to a FAQ section, are functioning correctly?

To ensure that links within a website are functioning correctly, PHP developers can use the PHP `file_get_contents()` function to check the HTTP status code of the URL. By checking for a status code of 200, developers can confirm that the link is valid and leads to a functional page. 

$url = 'https://www.example.com/faq';
$response = get_headers($url);

if (strpos($response[0], '200') !== false) {
    echo "Link to FAQ section is functioning correctly.";
} else {
    echo "Link to FAQ section is not working.";
}
