检测网站上的Flash内容

Question

I'm trying to create a function that checks if users have flash on there website. So far I have this:

$html = file_get_contents('http://www.test.com'); //users website
if(preg_match(".swf", $html, $matches)) {
    print("<pre>"); 
    print_r($matches); 
    print("</pre>");
}

But I don't get any results. Anyone got ideas? :)

Answer 1

<?php
$html = file_get_contents('http://www.disneylandparis.nl/'); //users website
$subject = $html;
$pattern = '/.swf/S';
preg_match($pattern, substr($subject,3), $matches);
print_r($matches);

Ruub, as Shankar Damodaran has suggested adjusting the regex works.
