Hey, to store values within cookies you must use the setcookie() function. You must also be able to store either the $_GET or $_POST superglobal array in the cookie but first you must convert it to a string. My suggestion would be to convert it to a JSON format over serializing it. Have a look at json_encode() and json_decode().

Most obviously when you retrieve the data you must use json_decode() to get back the orginal array.
