通过PHP访问AJAX数据

Question

I've been banging my head for 3 days trying to figure out how to access this AJAX JSON object via PHP. Here is the function that I have

$.ajax({
              type: "POST",
              url: "BPHCalcEnter.php",
              data: {'lastName': "Hello"},
              contentType: "application/json; charset=utf-8",
              dataType: "json",
               success: function (data) {
                    setTimeout(function (){
                    $(".container").html(data)
                    }, 1000);
               }
});

And here's the PHP code from BPHCalcEnter.php

  $myVar = $_POST['lastName'];
  json_decode($data);
  echo "var myval = foo($myVar);";

It shows var myVar = foo(); as if the variable is receiving nothing. Any help is appreciated. Thanks guys!

remove from ajax

 contentType: "application/json; charset=utf-8",
 dataType: "json",

You are not passing json from php.you are just echoing string
