When creating cookies with your page, there are specific parameters (cookies by the way are created using user-made code in PHP) that must be remembered so as not to fill up the hard disks of your client computers as they visit your website page again and again. The function setcookie is used with the following syntax:
setcookie(var1, var2, time)
The var 1 stands for the name of the cookie you are creating, with the var 2 containing the value of the said cookie and the last parameter is the time which specifies the amount of time it takes for the function to kill (terminate/delete) the cookie. A more defined and elaborate explanation of the function can be found on this page.
