您如何检测远程网站是否使用Flash？

Question

I am trying to write a tool that detects if a remote website uses flash using php. So far I have written a script that detects if embed or objects exist which give an indicator that there is a possibility of it being installed but some sites encrypt their code so renders this function useless.

include_once('simple_html_dom.php');
$flashTotalCount    = 0;
function file_get_contents_curl($url){

        $ch = curl_init();  
        curl_setopt($ch, CURLOPT_HEADER, 0);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);    
        $data = curl_exec($ch);
        curl_close($ch);    
        return $data;
    }

    $html = file_get_contents_curl($url);
    $doc = new DOMDocument();
    @$doc->loadHTML($html); 

foreach($html->find('embed') as $pageEmbed){
$flashTotalCount++;
}

foreach($html->find('object') as $pageObject){
$flashTotalCount++;
}

if($flashTotalCount == 0){  
echo "NO FLASH";    
}   
else{   
echo "FLASH";
}

Would anyone one know of a way to check to see if a website uses flash or if possible get header information that flash is being used etc.

Any advise would be helpful.

As far as I understand, flash can be loaded by javascript. So you should execute the web page. For this purposes you'll have to use tool like this: http://seleniumhq.org/docs/02_selenium_ide.html#the-waitfor-commands-in-ajax-applications

I don't think that it is usable from php.
