3 Answers. Cookies are always stored in the client. The path only sets restrictions to what remote pages can access said cookies. For example, if you set a cookie with the path “/foo/” then only pages in the directory “/foo/” and subdirectories of “/foo/” can read the cookie.
You use the setcookie() function in PHP to set a cookie in the browser. Then if your program can read that cookie, you know that cookies are enabled. The setcookie() function accepts several arguments to define the behavior of the cookie.
Note: The setcookie() function must appear BEFORE the <html> tag. Note: The value of the cookie is automatically URLencoded when sending the cookie, and automatically decoded when received (to prevent URLencoding, use setrawcookie() instead).

A cookie is often used to identify a user. A cookie is a small file that the server embeds on the user’s computer. Each time the same computer requests a page with a browser, it will send the cookie too. With PHP, you can both create and retrieve cookie values.

Cookies are usually set in an HTTP header but JavaScript can also set a cookie directly on a browser. Setting Cookie In PHP: To set a cookie in PHP,the setcookie() function is used. The setcookie() function needs to be called prior to any output generated by the script otherwise the cookie will not be set.
Just set the value of cookie to false in order to unset it, setcookie(‘cookiename’, false);
Accessing Cookies with PHP
Simplest way is to use either $_COOKIE or $HTTP_COOKIE_VARS variables. Following example will access all the cookies set in above example. You can use isset() function to check if a cookie is set or not.
What is PHP call function?
A PHP function provides code that a PHP script can call to perform a task, such as Count(), file_get_contents(), and header(). The PHP language supports both procedural and object-oriented programming paradigms.
There are two types of cookies, they are: Session Cookie: This type of cookies are temporary and are expire as soon as the session ends or the browser is closed. Persistent Cookie: To make a cookie persistent we must provide it with an expiration time.
Sessions in PHP normally do use cookies to function. But, PHP sessions can also work without cookies in case cookies are disabled or rejected by the browser that the PHP server is trying to communicate with.
Cookies can be an optional part of your internet experience. If you so choose, you can limit what cookies end up on your computer or mobile device. If you allow cookies, it will streamline your surfing. For some users, no cookies security risk is more important than a convenient internet experience.
If the cookie is on a domain you control: You will need to update that cookie by setting SameSite=None; Secure on it. See resources here and here. If the cookie is on a third-party domain: You should reach out to the owner of the domain setting that cookie and ask them to update it with SameSite=None; Secure.
Cookies are sent with every request, so they can worsen performance (especially for mobile data connections). Modern APIs for client storage are the Web Storage API ( localStorage and sessionStorage ) and IndexedDB.
