Problem with preg_match

[proseocontent]

Can anyone with PHP skills help me please.

with this you can chcekc the OVI Index (its for german sites)

http://www.xovi.de/ovi_api/?domain= 

the result are just numbers and a comma or point

now i wrote a function to implent the result in a page but i get no result to show

function getOVI($host) {
    $request = "http://www.xovi.de/ovi_api/?domain=" . urlencode($host) ;
    $data = getPageData($request);
        preg_match('/OVI \(([\d,]+)/si', $data, $l);
    $value = ($p[2]) ? $p[2] : "n/a";
    $string = "<a href=\"" . $request . "\">" . $value . "</a>";
    return $string;
} 

Hope anyone can find the mistake, i'm searching now for 2 hours

When I go to the site above I see "Keine Domain übergeben!".
Are you wanting to create a redirect script?

I got the solution. Thanks. I made a minimalistic mistake in code.

It is a script for checking OVI - its a new index in germany like Pagerank.
