Answer 1

You're already getting back something as useful than an array. Let's say your php does this:

<?php echo json_encode(array('John', 'Mary', 'Joseph')); ?>

Inside your function where you're alerting the data, you can get access to the elements like this:

alert(console.log(data[0])); //will alert "John"
alert(console.log(data[1])); //will alert "Mary"

If you need to loop through any of the elements, you can do so like this:

$(data).each(function(index) {
    console.log(this.toString());
});​

Answer 2

You are getting JSON out in that callback already. It doesn't look like it because when you "alert" it gets converted to a string that consists of a comma delimited list of the array elements.

You can see this by doing alert(data instanceof Array); which will spit out "true".
