        global $page, $paged, $post;
        $default_keywords = 'Php Developer forum, Php questions and answers, Java, iphone, Android developer forum'; // customize
        $output = '';
    
        // description
        $seo_desc = get_post_meta($post->ID, 'mm_seo_desc', true);
        $description = get_bloginfo('description', 'display');
        $pagedata = get_post($post->ID);
        if (is_singular()) {
            if (!empty($seo_desc)) {
                $content = $seo_desc;
            } else if (!empty($pagedata)) {
                $content = apply_filters('the_excerpt_rss', $pagedata->post_content);
                $content = substr(trim(strip_tags($content)), 0, 155);
                $content = preg_replace('#\n#', ' ', $content);
                $content = preg_replace('#\s{2,}#', ' ', $content);
