PHP

echo json_encode($cars);

JavaScript

Native:

var foo = JSON.parse(xmlhttp.responseText);

With jQuery:

var foo = $.parseJSON(xmlhttp.responseText);

//or

$.getJSON(url, function(data){

    //data is your array

});

UPDATE

if(xmlhttp.readyState==4 && xmlhttp.status==200){

     //document.getElementById('addIO').innerHTML+=xmlhttp.responseText;

    var cars = JSON.parse(xmlhttp.responseText);  //cars will now be the array.

     //Do whatever you want here.

    $(#addIO).html(cars.join(, ));     //Join array with ,  then put it in addIO

}

If you want to use jQuery, put this in <head>:

<script type=text/javascript src=link/to/the/file/jquery.js></script>
