Question

I've url as following format

http://domain.com/redirect?url=http://thirdpartydomain.com?aff_id=4234324&url=http://storesite.com/list/page/1

Here I want to get the value of first url key i,e.

http://thirdpartydomain.com?aff_id=4234324&url=http://storesite.com/list/page/1

What's best to get this,

I've tried suggested methods over SO but none of them worked me.

$UrlYouNeed = substr($originalURL, strpos($originalURL, "=") + 1);
