1,234,567

I need to get statsTopHi data? but dont know how to do it, i'm new to php and dont know anything about curl.

    $handle = curl_init();
    curl_setopt($handle, CURLOPT_URL, "my url");
    curl_setopt($handle, CURLOPT_RETURNTRANSFER, true);
    $html = curl_exec($handle);
    curl_close($handle);

   $DOM = new DOMDocument;

   $DOM->loadHTML($html);

   //get all span
   $items = $DOM->getElementsByTagName('span');

   //display all span text
   for ($i = 0; $i < $items->length; $i++)
        echo $items->item($i)->nodeValue . "
";
?>

Using this i parse all span content, but need to get only class="statsTopHi"
