Answer 1

array_merge your arrays and then use the following code as an example of how you can sort it.

function sortDate($val1, $val2)
{
    if ($val1['date'] == $val2['date']) {
        return 0;
    }

    return (strtotime($val1['date']) < strtotime($val2['date'])) ? -1 : 1;
}

$array = array(
    array('date' => '2012-01-10'),
    array('date' => '2011-01-10'),
    array('date' => '2012-01-01')
);

usort($array, "sortDate");
print_r($array);
