How can a user create a cookie on their website using PHP?

To create a cookie on a website using PHP, you can use the setcookie() function. This function takes in parameters for the cookie name, value, expiration time, path, domain, and secure flag. Once the setcookie() function is called with the desired parameters, a cookie will be created and stored on the user's browser.

// Set a cookie with name 'user' and value 'JohnDoe' that expires in 1 hour
setcookie('user', 'JohnDoe', time() + 3600, '/');
