you're mixing js , php, , it's deadly combination. js client-side language php sever side language.
every thing write in php executed server , write in js executed client side.
first solution use ajax calls connect php script js. call ajax function on click of button calls php script on server side save cookie.

another solution perform operations on client side save/retrive cookie.

doing on server-side preferable gives more security client side code.
