What is the purpose of using a checkbox to install a cookie in a PHP form?

When using a checkbox to install a cookie in a PHP form, the purpose is to give users the option to consent to the use of cookies on the website. By using a checkbox, users can actively choose to allow or deny the installation of cookies, which helps ensure compliance with data privacy regulations such as GDPR. To implement this, you can add a checkbox to your form that users can select to give their consent before setting the cookie. 

<?php
if(isset($_POST['submit'])){
    if(isset($_POST['cookie_consent'])){
        setcookie('cookie_name', 'cookie_value', time() + (86400 * 30), '/'); // Set cookie for 30 days
    }
}
?>

<form method="post">
    <label for="cookie_consent">I consent to the use of cookies</label>
    <input type="checkbox" id="cookie_consent" name="cookie_consent">

    <input type="submit" name="submit" value="Submit">
</form>
