File_Get_Contents problem with url and variable being passed

I've got a tiny script that is failing on me, and i'm not sure why. Getting your run of the mill:

<BR><B>Parse error</B>: syntax error, unexpected T_STRING in <B>/home/theriv00/domains/ccddd.com/public_html/cacheparse.php</B> on line <B>4</B><BR>

Here's the code:

<?php
$n= $_GET['n'];
$data = file_get_contents('http://webcache.googleusercontent.com/search?sourceid=navclient&ie=UTF-8&q=cache=http://www.'.$n.');
$regex = '/snapshot of the page as it appeared on (.+?) GMT/';
preg_match($regex,$data,$match);
echo $match[1];
?>

Why would the script be failing on line 4? (the regex entry). Something tells me it's the line above with the file_get_contents call.

I have a program that is calling this script and is passing a domain name ($n) to the file_get_contents) call. The tricky part is that i'm having the script parse google but passing the domain name as the variable. Any ideas where I'm falling apart?

http://www.mysite.com/cacheparser.php?n=domain.com

 

Use it as this :
$data = file_get_contents('http://webcache.googleusercontent.com/search?sourceid=navclient&ie=UTF-8&q=cache=http://www.'.$n);

 

//$n= $_GET['n'];

$n = "yahoo.com"; // or could be http://www.yahoo.com either way is fine

$data = file_get_contents("http://webcache.googleusercontent.com/search?q=cache:$n");

//echo $data;

$regex = '/snapshot of the page as it appeared on (.+?) GMT/';
preg_match($regex,$data,$match);
echo $match[1]; // 2 Dec 2010 01:42:33;

PHP:

EDIT: or cURL

//$n= $_GET['n'];

$n = "yahoo.com"; // or could be http://www.yahoo.com either way is fine

$url = "http://webcache.googleusercontent.com/search?q=cache:$n";

$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, '5');
$data = curl_exec($ch);
curl_close($ch);

//echo $data;

$regex = '/snapshot of the page as it appeared on (.+?) GMT/';
preg_match($regex,$data,$match);
echo $match[1]; // 2 Dec 2010 01:42:33

PHP:

On different servers you might get different date formats, so results could be Dec 2, 2010 01:42:33 if that's a problem lets us know.

 

voda, thanks for the help again. It's not so much the end result, it's the in between that's teaching me. Thanks
