Retrieving variables that contain links form URL

Say I have the following URL:

http://www.domain.net/?page=offsite&url=https://www.domain.com/LoanRequest/page.aspx?CUID=10414424&LOID=850&ChannelId=4078715104014180815

When I do the following:

echo ($_GET["url"]);

I get the following:

https://www.domain.com/LoanRequest/page.aspx?CUID=10414424

It isn't the entire link and I know why - it assumes the "&" is for a new variable...

How do I grab the entire link or is there certain way the original link needs be coded?

This is what we ended up doing based on TecBrat's suggestion:

//get URL
$offsite_url = $_SERVER['REQUEST_URI'];

//break about URL
$offsite_url = str_replace('/?page=offsite&url=', '' , $offsite_url);

//clean input
$offsite_url = cleaninput($offsite_url);

(cleaninput is a sanitizing function)

I don't think it is the ideal solution (maybe it is - open to feedback), but it appears to be working. urlencode seems like a better solution, but that wasn't an option.

If the structure of the offsite url is unpredictable, then I'd use $_SERVER['QUERY_STRING'] and pull off what I need with string functions. If it is predictable, the I'd use the answer given by Maxiums2012 unless you also control the link, then I'd suggest, as others have, to urlencode the offsite url before sending it.

If you create the original link, you should pass all query vars from url encode

Like 

$q_url = 'https://www.domain.com/LoanRequest/page.aspx?CUID=10414424&LOID=850&ChannelId=4078715104014180815';

$url = 'http://www.domain.net/?page=offsite&url='.urlencode($q_url);

Then by $_GET["url"] you should get the whole url

The URL you have is incorrect, then.

The URL base URL is

http://www.domain.net/

and its parameters are

page=offsite
url=https://www.domain.com/LoanRequest/page.aspx?CUID=10414424
LOID=850
ChannelId=4078715104014180815

If you want the LOID and ChannelID to be associated with that url= parameter, then it should be encoded with urlencode() as

http://www.domain.net/?page=offsite&url=https://www.domain.com/LoanRequest/page.aspx?CUID=10414424&LOID=850&ChannelId=4078715104014180815

Can you try this:

$link = $_GET['url'] . "&LOID=" . $_GET['LOID'] . "&ChannelID=" . $_GET['ChannelID'];

The way your original URL is defined, 'url' will only be treated as one of the GET parameters which means you need to separately get other GET parameters in order to construct the complete URL. UPDATE: changed the url variable according to suggestion from Ben Fortune.
