使用范例

<?phpinclude 'seoreport.php';ini_set('max_execution_time', 180); $url = (isset($_GET['url']))?$_GET['url']:'http://phpclasses.org'; $meta_tags = seoreport::meta_info($url); //die(var_dump($meta_tags)); //first check if site online if ($meta_tags!==FALSE) { $stats = array(); $stats['meta'] = $meta_tags; $stats['alexa']['rank'] = seoreport::alexa_rank($url); $stats['alexa']['links'] = seoreport::alexa_links($url); $stats['domain']['WOT_rating'] = seoreport::WOT_rating($url); $stats['domain']['domain_age'] = seoreport::domain_age($url); $stats['social']['twitter'] = seoreport::tweet_count($url); $stats['social']['facebook'] = seoreport::facebook_shares($url); $stats['google']['page_rank'] = seoreport::page_rank($url); $stats['google']['page_speed'] = seoreport::page_speed($url); $stats['google']['pages'] = seoreport::google_pages($url); $stats['google']['links'] = seoreport::google_links($url); var_dump($stats); } else 'Site not online.
