    var xmlhttp;
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.open("POST","new_map.php",true);
xmlhttp.send(cur_entry_string);

$massage = $_POST[cur_entry_string];

Maybe you should have a look at an AJAX tutorial http://www.w3schools.com/ajax/default.asp and if that is not what you want to do you can also look into JSON
