How can PHP developers ensure that cookies are accepted by users without compromising security or privacy?

To ensure that cookies are accepted by users without compromising security or privacy, PHP developers can inform users about the use of cookies on their website and obtain explicit consent before setting any cookies. This can be done through a cookie consent banner or pop-up that allows users to accept or reject cookies. Additionally, developers should only set necessary cookies for the website to function properly and provide users with the option to manage their cookie preferences. 

<?php
// Check if user has accepted cookies
if(isset($_COOKIE['cookie_consent'])) {
    // Set necessary cookies for the website
    setcookie('example_cookie', 'value', time() + 3600, '/', 'example.com', true, true);
} else {
    // Display cookie consent banner or pop-up
    echo '<div id="cookie-consent">This website uses cookies. <button onclick="acceptCookies()">Accept</button></div>';
}

// JavaScript function to set cookie consent
echo '<script>
function acceptCookies() {
    document.cookie = "cookie_consent=true; expires=Fri, 31 Dec 9999 23:59:59 GMT; path=/";
    document.getElementById("cookie-consent").style.display = "none";
}
</script>';
?>
