As you said the array is in php file which is called via ajax, you can simply decode the json encoded string and retrieve the array with keys and values respectively.

Simply use json_decode() function to retrieve the array.

Code in javascript "json.js" is required. you can download this.

var votedCommentString = getCookie("votedComment"); // get value of voted comment cookie 

votedComment = JSON.parse(votedCommentString); // extract json object into array

votedComment[votedComment.length] = id; // add more data in array

var cookieData = JSON.stringify(votedComment); // convert array into json object

setCookie("votedComment", cookieData, 365); // and again set cookie

In PHP you can access this in following way

$cookieData = (array)json_decode($_COOKIE["votedComment"]); // extract json object into array

print_r($cookieData);

Use 

json_encode($array_variable) // to convert array in to json
