如何将json数组变量数据复制到php变量？

Question

This is a web page for student results and 3 fields data i.e stu_class, section, exam is sending to controller and a json array data variable is coming back from controller to this page now i wanted to show that json variable's data on the webpage. So help me how to do so?

$(document).ready(function(){

$('#examination').change(function(){

  var exam = $('#examination').val();
  $('#exam').val(exam);
  });

$('#enter').click(function(){
 var stu_class = $('#stu_class').val();
 var section = $('#section').val();
 var exam = $('#examination').val();

  $.ajax(
     {
       type : "POST",
       dataType: "json",
       url : "<?php echo base_url('index.php/marksheet/student_result_database'); ?>",

       data : {
              stu_class : stu_class,
              section : section,
              exam : exam
          },
       success: function(stu_data)
        {
          var items = [];
          $.each( stu_data, function( key, val ) {   
               items.push( "<li id='" + key + "'>" + val['student'] + "</li>" );
             });

             alert(items);

          }
       });
      });

});

And i need to copy the data of stu_data variable of jquery to php variable $stu_data so that i can run a loop to show the values in below fields like this-

<?php foreach($stu_data as $data): 
echo $data['id']; 
echo $data['student'];

Something like this. So programmers please help me..!

json_decode($str, true) -> turns a json-object into a php assoc array.

json_decode($str, false) -> turns a json-object into a php object.
