In what ways can I make my website compliant with cookie handling regulations and privacy policies?

To make your website compliant with cookie handling regulations and privacy policies, you can implement a cookie consent banner that informs users about the use of cookies on your site and allows them to accept or reject them.

<?php
if (!isset($_COOKIE['cookie_consent'])) {
    echo '<div id="cookie-banner">
            <p>This website uses cookies to ensure you get the best experience on our website.</p>
            <button onclick="acceptCookies()">Accept</button>
            <button onclick="rejectCookies()">Reject</button>
          </div>';
}

if (isset($_POST['cookie_consent'])) {
    if ($_POST['cookie_consent'] == 'accept') {
        setcookie('cookie_consent', 'accepted', time() + 86400 * 30, '/');
    } else {
        setcookie('cookie_consent', 'rejected', time() + 86400 * 30, '/');
        // Clear any existing cookies
        foreach ($_COOKIE as $key => $value) {
            setcookie($key, '', time() - 3600, '/');
        }
    }
}

function acceptCookies() {
    document.getElementById('cookie-banner').style.display = 'none';
    // Add code to set cookies here
}

function rejectCookies() {
    document.getElementById('cookie-banner').style.display = 'none';
    // Add code to reject cookies here
}
?>
