Parse blog to find keywords

We are using php to find relevent blogs based on keywords

$blog_data = array(
            'campaign_id' =>$campaign['campaign_id'],
            'campaign_name' => $campaign['campaign_name'],

            'extra_keywords' => $extra_keywords,
            'page_url' => $get_blog['page_url'],
            'page_id' => $get_blog['id'],
            'html' => $get_blog['page_text']
        );
        $blog_parse_result = parse_blog_data($blog_data);

{
    show( "Parse text for: ".$data['page_url']);


    $keywords = array_merge($data['mandatory_keywords'],$data['extra_keywords']);

    #    show( "\n************** END: NO KEYWORDS {$data->campaign_name} ($data->campaign_id) ****************\n\n");
        return;
    }

    require_once("blog_parser/phpQuery.php");
    $doc = phpQuery::newDocumentHTML($data['html']);
