How can I get my curl statement to correctly read google image guesses?
===

I am creating a little code that reads Google's best guess for images on their image search.

Click on the link so you can see what I am talking about.
http://images.google.com/searchbyimage?image_url=http://static.filestube.com/files/images/logo3.gif

If you click the link you can see that the results say: Best guess for this image: filestube logo

I want to be able to pull the best guess and return it

HERe IS MY CODE ThAT DOESNT WORK


    $ch = curl_init("http://images.google.com/searchbyimage?image_url=http://static.filestube.com/files/images/logo3.gif");
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch,CURLOPT_RETURNTRANSFER, 1);
    $result = curl_exec($ch);
    curl_exec($ch);
    curl_close($ch);
    preg_match("Best guess for this image:&nbsp;(.*)</a>", $result, $matches);
    if(empty($matches)){
		echo("No guess on this image. <br />");
	} else{
	    echo("Best guess for this image:");
		print_r($matches);
	}


I keeps on returning no guess
