How to store a value returned by Ajax into a session

I'm making an online booking form, where I use Ajax to retrieve the total price based on arrival date, departure date and number of guests (see image below). The form has 5 pages, and I would like to store the total price in a session, so that I could display it on all pages.

My Ajax call looks like this:
mygetrequest.open("GET", "get_price.php?arrival="+arrivalvalue+"&departure="+departurevalue+"&guests="+guestsvalue+"&apartment_id="+apartmentidvalue, true)

I tried to store the total price in a PHP session inside get_price.php in the end of the file before echoing the price for the booking form, but it didn't work. Should I be using Javascript instead, and how would that be done? I've pasted the full Ajax code below.
function showPrice() {
  if(document.getElementById("departure").value.length!=0) {
	function ajaxRequest(){
		 var activexmodes=["Msxml2.XMLHTTP", "Microsoft.XMLHTTP"] //activeX versions to check for in IE
		 if (window.ActiveXObject){ //Test for support for ActiveXObject in IE first (as XMLHttpRequest in IE7 is broken)
		  for (var i=0; i<activexmodes.length; i++){
			return new ActiveXObject(activexmodes[i])
			//suppress error
		 else if (window.XMLHttpRequest) // if Mozilla, Safari etc
		  return new XMLHttpRequest()
		  return false
	var mygetrequest=new ajaxRequest()
	 if (mygetrequest.readyState==4){
	  if (mygetrequest.status==200 || window.location.href.indexOf("http")==-1){
	   alert("An error has occured making the request")
	var apartmentidvalue=encodeURIComponent(document.getElementById("apartment_id").value)
	var arrivalvalue=encodeURIComponent(document.getElementById("arrival").value)
	var departurevalue=encodeURIComponent(document.getElementById("departure").value)
	var guests = document.getElementById("guests")
	var guestsvalue = guests.options[guests.selectedIndex].value
	mygetrequest.open("GET", "get_price.php?arrival="+arrivalvalue+"&departure="+departurevalue+"&guests="+guestsvalue+"&apartment_id="+apartmentidvalue, true)
