在PHP中检索JSON的问题

Question

My Javascript sends an array in JSON to dbinsert.php

function SendTableToPHP() {
  //Store HTML Table Values into Multidimensional Javascript Array Object
  var TableData;
  TableData = storeTblValues()

  function storeTblValues() {
    var TableData = new Array();
    $('#itemtable tr').each(function(row, tr) {
      TableData[row] = {
        "ritem": $(tr).find('td:eq(0)').text(),
        "rqnty": $(tr).find('td:eq(1)').text(),
        "rbale": $(tr).find('td:eq(2)').text(),
        "ramt": $(tr).find('td:eq(3)').text(),
        "rrmk": $(tr).find('td:eq(4)').text(),
      } //tableData[row]
    });

    TableData.shift(); // first row will be empty - so remove
    //console.log(TableData);
    return TableData;
  }

  var Data;
  Data = $.toJSON(TableData);
  console.log(Data);

  $.ajax({
    type: "POST",
    url: "dbinsert.php",
    data: "pTableData=" + Data,
    success: function(msg) {
      alert(msg) //return value stored in msg variable "success";
    } //success
  });
};

The output result also alerts showing the response from dbinsert.php: Output Showing json created

<?php
  // Unescape the string values in the JSON array
  $tableData = stripcslashes($_POST['pTableData']);

  // Decode the JSON array
  $tableData = json_decode($tableData,TRUE);

  // now $tableData can be accessed like a PHP array
  echo $tableData[1]['ritem'];
  echo $tableData[2]['ritem'];
  echo $tableData[3]['ritem'];

  $dat = $_POST['podat'];
  echo $dat;
?>

However the output is showing only date ($dat) and what i want to display array from that json. i need to insert data in database from that array thats why i want to check if array isdisplaying ok or not.
