The Setcookie () function sends an HTTP cookie to the client.

A cookie is a variable that is sent by the server to the browser. Cookies are usually small text files that the server embeds into the user's computer. This cookie is sent whenever the computer requests a page through the browser.

The name of the cookie is specified as a variable of the same name. For example, if the cookie being sent is named "name", a variable named $user is automatically created, containing the value of the cookie.

The cookie must be assigned before any other output is sent. If successful, the function returns True, otherwise it returns false
