//Create function which returns value of any parameters variable
function GetURLParameter(sParam) {
    var sPageURL = window.location.search.substring(1),
        sURLVariables = sPageURL.split('&');

    for (var i = 0; i < sURLVariables.length; i++) {
        var sParameterName = sURLVariables[i].split('=');
        if (sParameterName[0] == sParam)   {
          return sParameterName[1];
        }

//variable
var lang = GetURLParameter('php');
var blog = GetURLParameter('techtalk');
