Thanks to all, on the net, i was able to get the redirect working, with some help.. code below

I added this to the top of the code, now space or no space it works good.

$mob = str_replace(”+”, “_”, $_SERVER['QUERY_STRING']);
$url = “http://example.com/pfinder?” . “$mob”;

and at the end i added this to go to the page i want
$fin = get_final_url($url);
$mov = parse_url($fin, PHP_URL_QUERY);
sleep(5);
header(”Location: http://enample1.com?$mov“);

works fine..
But now i have a problem, the server i was to put this on does not support PHP. (server side)
I know this is not the right forum, but can any one help me to get this done in javascript (client side)

Thanks for your work. I recently faced a similar problem and your solution made my day lots of easier.

Interesting. I added syntax highlighting to your code.

Tried and tested function (follows javascript redirects as well):

function get_final_url( $url, $timeout = 5 )
{
	$url = str_replace( "&", "&", urldecode(trim($url)) );
 
	$cookie = tempnam ("/tmp", "CURLCOOKIE");
    $ch = curl_init();
    curl_setopt( $ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20041001 Firefox/0.10.1" );
	curl_setopt( $ch, CURLOPT_URL, $url );
	curl_setopt( $ch, CURLOPT_COOKIEJAR, $cookie );
	curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, true );
	curl_setopt( $ch, CURLOPT_ENCODING, "" );
	curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
	curl_setopt( $ch, CURLOPT_AUTOREFERER, true );
	curl_setopt( $ch, CURLOPT_CONNECTTIMEOUT, $timeout );
	curl_setopt( $ch, CURLOPT_TIMEOUT, $timeout );
	curl_setopt( $ch, CURLOPT_MAXREDIRS, 10 );
	$content = curl_exec( $ch );
	$response = curl_getinfo( $ch );
	curl_close ( $ch );
 
	if ($response['http_code'] == 301 || $response['http_code'] == 302)
	{
		ini_set("user_agent", "Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20041001 Firefox/0.10.1");
		$headers = get_headers($response['url']);
 
		$location = "";
		foreach( $headers as $value )
		{
			if ( substr( strtolower($value), 0, 9 ) == "location:" )
				return get_final_url( trim( substr( $value, 9, strlen($value) ) ) );
		}
	}
 
 
	if (	preg_match("/window\.location\.replace\('(.*)'\)/i", $content, $value) ||
			preg_match("/window\.location\=\"(.*)\"/i", $content, $value)
	)
	{
		return get_final_url ( $value[1] );
	}
	else
	{
		return $response['url'];
	}
}

Thanks for the fix. I hadn’t considered relative URLs at all.

Bug fix:

if (preg_match(’/^Location: (.+?)$/m’, $response, $matches)){
if ( substr($matches[1], 0, 1) == “/” )
return $url_parts['scheme'] . “://” . $url_parts['host'] . trim($matches[1]);
else
return trim($matches[1]);

} else {
return false;
}

I’ve no idea why this would happen. I tried a few tests myself using a query that contains a space, and it was processed correctly. Maybe you can give me a real example that I could test?

hi,
i did a echo $response; after the fclose($sock) and i saw that the first url was shown as query=val1 val2, noticed that the “+” was gone, i tried to replace the space with%20 still same only val1 was picked. any comments

Hmm, I’m not sure I completely understand what you’re trying to do, but I don’t see why the second part of the variable wouldn’t be captured. Have you tried doing something like

print_r($_GET);

to verify that it’s really discarded by the server, instead of a bug somewhere in your script?
