jQuery access Ajax Response from PHP function

Question

I have a PHP function where I pass a variable to and it returns an array containing a start date and end date.

<?php
 function dateRangeTimeFrame($var1){
  ...

  $date['startDate'] = $startDate;
  $date['endDate'] = $endDate;

  return $date;
 }
?>

I am also trying to use this PHP function in an AJAX call so I can reuse the code. I have added this to the beginning of the page:

if (isset($_POST['dateFunction'])) {
  print_r(dateRangeTimeFrame($_POST['dateFunction']));
}

My jQuery code is as follows:

$.ajax({
    url: 'includes/functions.php',
    type: 'post',
    data: { "dateFunction": theDate},
    success: function(response) { 
        console.log(response['startDate']); 
        console.log(response.startDate); 
    }
});

My issue is that I do not know how to access the response that the php function is returning.

Here is the response I am getting from the PHP function:

Array
(
  [startDate] => 2015/01/17
  [endDate] => 2015/02/16
)

How would I go about getting these 2 vars from the PHP response?

You need to use JSON. Your Javascript natively understands and can parse it

if (isset($_POST['dateFunction'])) {
   echo json_encode(dateRangeTimeFrame($_POST['dateFunction']));
}

And your jQuery (note I added dataType)

$.ajax({
    url: 'includes/functions.php',
    dataType: 'json',
    type: 'post',
    data: { "dateFunction": theDate},
    success: function(response) { 
        console.log(response.startDate); 
    }
});
