CodeIgniter: problem using foreach in view

Question

I have a model and controller who gets some data from my database and returns the following array

Array
(
    [2010] => Array
        (
            [year] => 2010
            [months] => Array
                (
                    [0] => stdClass Object
                        (
                            [sales] => 2
                            [month] => Apr
                        )

                    [1] => stdClass Object
                        (
                            [sales] => 1
                            [month] => Nov
                        )

                )

        )

    [2011] => Array
        (
            [year] => 2011
            [months] => Array
                (
                    [0] => stdClass Object
                        (
                            [sales] => 1
                            [month] => Nov
                        )

                )

        )

)

It shows exactly what it should show but the key's have different names so I have no idea on how to loop through the years using foreach in my view. Arrays is something I'm not that good at yet :(

this is the controller if you need to know:

    function analytics()
    {
        $this->load->model('admin_model'); 
        $analytics = $this->admin_model->Analytics();
        foreach ($analytics as $a):
            $data[$a->year]['year'] = $a->year;
            $data[$a->year]['months'] = $this->admin_model->AnalyticsMonth($a->year);
        endforeach;

        echo"<pre style='text-align:left;'>";
        print_r($data);
        echo"</pre>";

        $data['main_content'] = 'analytics';
        $this->load->view('template_admin', $data);
    }//end of function categories()

Answer 1

put the arrays of years in a separate index in the array so you can isolate it

foreach ($analytics as $a) {
    $data['dates'][$a->year]['year'] = $a->year;
    $data['dates'][$a->year]['months'] = $this->admin_model->AnalyticsMonth($a->year);
}

Then you can loop through that without having to worry about the other data

<?php foreach( $dates as $year => $year_content  ): ?>
<h2><?php echo $year ?></h2>

<?php foreach( $year_content['months'] as $months ): ?>
<h3><?php echo $months->month ?> - <?php echo $months->sales ?></h3>
<?php endforeach; ?>

<?php endforeach; ?>
