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.
