Retrieve SE rank using PHP

[johncook]

I've written some code that retrieves from a search engine the number of websites that match a certain keyphrase. Eg -

function LoadPage($KeyPhrase)
	{
	$URLPath = "http://www.google.com/search?sourceid=navclient&ie=UTF-8&oe=UTF-8&q=%22$KeyPhrase%22";
	$Handle = fopen($URLPath, "rb");
	$Contents = "";
	do
		{
		$Data = fread($Handle, 8192);
		if (strlen($Data) == 0)
			{
			break;
			}
		$Contents .= $Data;
		} while (true);
	fclose($Handle);
	return $Contents;
	}

$KeyPhrase = str_replace(" ","+",$KeyPhrase);
$Content = LoadPage($KeyPhrase);
if (preg_match('/of about (.*?) for/',$Content,$matchesarray))
	echo $matchesarray[1];

Would it be possible to amend this code to work out the SE ranking of a URL for that keyphrase? Or is there another way to do it? Any tips would be appreciated :-)

Thanx for the link although the forum doesn't seem to exist anymore. I notice digitalpoint have a similar ranking tool but I was looking to do it myself (and not just for google, for several search engines).
