JQuery object of an array to string -

i retrieved object of array code behind(php) jquery , get:

array (     [0] => stdclass object         (             [mfid] => 1             [mfname] => customer id             [ftid] => 1             [dtid] => 1             [mfkey] => 0             [mfwskey] =>              [mfwsname] =>              [mfrequired] => 1             [mfdefaultvalue] =>              [mfmin] => 0             [mfmax] => 0             [mfduedate] => 0             [mftobepaid] => 0             [mfmaxlength] => 50             [mforderno] => 1             [mfstatus] => 1         )  ) 

i want mfname array input object, lets say

$("#fname").val(data[0]['mfname']); 

but not work.

usually in php before returning client,

    $val = $array[0]->mfname; 

how can in jquery?

// return json encoded array in php side

var arr = json.parse(yourarray); alert(arr[0].mfname);  

hope find using this
