Answer 1

Use usort. The following is essentially the basic example from the manual:

function cmp($a, $b) {
    if ($a['avg_pred_error'] == $b['avg_pred_error'])
        return 0;

    return ($a['avg_pred_error'] < $b['avg_pred_error']) ? -1 : 1;
}

// Sort (LOW to HIGH) and print the resulting array
usort($array, 'cmp');
print_r($array);
