How best to pass a complex JavaScript object to PHP?

I have a JavaScript object that contains two arrays. One of the arrays is an array of objects and the other is just a straight forward array.

i.e.

obj = {
  arr1: [
    {
      a1: 'val',
      a2: 'val'
    },
    {
      b1: 'val',
      b2: 'val'
    }
  ],
  arr2: ['a', 'b', 'c']
};

I am trying to pass this whole lot as on object to PHP to store in a MySQL database. How best should I go about this so that I can eventually pass it back to JavaScript in the same structure as it started out as?

Many thanks for any help.

JSON

Here is an example to convert an object into a string & back in javascript

it should not contain functions.

var obj={a:'a',b:'b',array:[1,2,3,4]};
var string=JSON.stringify(obj);

// or back to object 
var obj=JSON.parse(string);

POST that string.

Then in php you can do the same.

<?php
$obj=json_decode($_POST['string']);

// back to object
// $string=json_encode($obj);
?>

if you want a post example just ask.. or if you have any questions.
