Cookies are very easy in php...

The simplest way to set a cookie is:

setcookie("CookieName","Cookie Value');

to delete a cookie, use:

setcookie("CookieName");

To get the value of a cookie, PHP will automatically give you all of the cookies for your url automatically, eg. The cookie set above will be given to your script simply by looking at the value of $CookieName

Of course, there are more options... To set an expiration date of a cookie, use:

setcookie("CookieName","Cookie Value", time()+3600);

This will set this cookie to expire in 1 hour (3600 seconds) from now (time()).

Still, there are even more things you can do, but they are not commonly used, so i will not cover them here...
