PHP array to JavaScript using JSON object - returns null

Question

I've got an array in PHP which I'm passing to my view for use within the JavaScript.

So what I've got is:

stdClass Object
(
    [tones] => Array
    (
        [0] => Array
        (
            [id] => 114
            [sleep_session_id] => 55
            [responded_to] => 
            [in_bed] => 1
            [created] => 1316443267104
            [inserted] => 2011-09-19 14:43:04
        )
    )
)

$(function () {
    var tones = $.parseJSON(<?php echo json_encode($this->tones); ?>);
    alert(tones);
});

Which results in something along the lines of:

<script type="text/javascript">
    $(function () {
        var tones = $.parseJSON([{"id":114,"sleep_session_id":55}]);
        alert(tones);
    });
</script>

All I'm getting back is null, the jQuery is definately loaded and I've checked the JSON in jsonlint.com and it appears valid

Hope you can help me out

If your server-side data are in JSON, there's no need to use $.parseJSON in Javascript.

$(function () {
    var tones = <?php echo json_encode($this->tones); ?>;
    alert(tones);
});

parseJSON parses a JSON string, so enclose your encoded array in quotes :

$(function () {
    var tones = $.parseJSON('<?php echo json_encode($this->tones); ?>');
    alert(tones);
});

See this example
