What is a cookie?

Have you ever wondered how websites know who you are? It’s all about cookies. “Cookies” are small files on your computer that websites can read. They place those files to identify you — tracking you and your accounts through the internet.

Today, cookie use is actually a little controversial. To adhere to European laws, you need to ask whether you can place a cookie on a user device. Tracking cookies are increasingly being blocked on mobile devices like iOS and Android. Cookies are still very important, but you have to be careful about how you use them and when.

How do you use PHP SETCOOKIE?

On the surface, using PHP SETCOOKIE is very simple. Here’s the formula from the PHP manual:

	setcookie($name, $value, $expires_or_options, $path, $domain, $secure, $http_only);

To set a cookie, you would usually use code like this:

	setcookie("Hello_World", "Hello, World!", time()+86400, "/", "growthnestmedia.site", 1, 1);
