A cookie is set using the setcookie()
function. Since cookies are part of the HTTP header, you must set any cookies before sending any output to the browser.
Example:
setcookie("user", "Tom", time() + 86400, "/"); // check syntax for function params
Description:
user
Tom
/
A created or modified cookie can only be accessed on subsequent requests (where path and domain matches) as the superglobal $_COOKIEis not populated with the new data immediately.
