php - AJAX POST two dimensional array to a Zend controller and recieving it -

hi in view creating 2 dimentional array in javascript , passting update controller follows :

array in javascript

item[0][0] = null; item[0][1] = 1; item[1][0] = 2; item[1][0] = 3; 

alert (item); show ,1,2,3

passing zend controller :

$.ajax({             type: "post",             url: "admin/navigation/update",             data: item,             success: function(data) {                 alert(data);             },             error: function() {                 alert("failure");             }         });         return false;     } 

how can receive update controller , assign php array as

public function updateaction() {         $data = $this->_request->getpost();        //code should come here  array(       item1(        array(         value1 = item[0][0] //from javascript array         value2 = item[0][1]        )      )       item2(        array(         value1 = item[1][0]         value2 = item[1][0]        )       )     ) } 

i'm n00b in zend , appriciated :)

instead of below code:

$data = $this->_request->getpost(); 

use following code:

$data = $this->_request->getparams(); print_r($data); 

this give array sending javascript.
