Headers problem

Hello.

I have to prepare some analyzer, which would analyze content of given url.
So my PHP files are opening given url as a file, and read it into variable.
The problem is that it doesn't work with all given pages. Some pages require
to know what kind of browser (user agent) is opening page, and if there is
no such information they don't display anything, and my variable is empty. I
have tried to use curl with something like this:

$file="my_url";

$agent="Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)";
$ch = curl_init();
curl_setopt($ch, CURLOPT_USERAGENT, $plik);
$ret = curl_exec($ch);

Nothing happens - the site is not readed. If I add in curl section something
like this

curl_setopt($ch, CURLOPT_URL, $plik);

It shows me all the page, and I don't want to be shown, I wan't only to be
read into string variable.
If you know some way to do this, please help.

Couldn't you grab it with output buffering?
if you had something like this:

ob_start();
.... your code here ...
$str = ob_get_contents();
ob_end_clean();

then I'd imagine that instead of showing the page, the source would be
stored in $str...

$url = 'http://www.google.nl/';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERAGENT, $agent);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$ret = curl_exec($ch);
