I have the following method that creates and returns markup for my pagination links in PHP.

public function getPaginationLinks($options) {
    if($options['total_pages'] > 1) {
        $markup = '<div class="pagination">';

        if($options['page'] > 1) {
            $markup .= '<a href="?page=' . ($options['page'] - 1) . ((isset($options['order_by'])) ? "&sort=" . $options['order_by'] : "") . '">< prev</a>';
        }       

        for($i = 1; $i <= $options['total_pages']; $i++) {

            if($options['page'] != $i) {
                $markup .= '<a href="?page='. $i . ((isset($options['order_by'])) ? "&sort=" . $options['order_by'] : "") . '">' . $i . '</a>';
            }
            else {
                $markup .= '<span class="current">' . $i . '</span>';
            }
        }

        if($options['page'] < $options['total_pages']) {
            $markup .= '<a href="?page=' . ($options['page'] + 1) . ((isset($options['order_by'])) ? "&sort=" . $options['order_by'] : "") . '">next ></a>';
        }

        $markup .= '</div>';

        return $markup;
    }
    else {
        return false;
    }
}

I just recently discovered (to my surprise) that i had reached 70+ pages which means that there are now 70+ links showing up at the bottom..

I'm wondering if someone can help me break this up.. I'm not sure how most pagination works as far as showing the numbers if im on say.. page 30, ideas?
