Answer 1

If you had the following

$double_url = 'http://www.mysite.com/test.php?http://www.anotherwebsite.com';

then you could do this

$second_url = substr(strstr($double_url, '?http'), 1);

OR this

$second_url = preg_replace('/.*\?(http.*)/', '$1', $double_url);

OR this

$second_url = substr($double_url, strpos($double_url, '?http')+1);

OR many other approaches that will give you the same result.

I am concerned with using ? as a delimiter between URLs because the ? is a valid and important part of the full URI. For this reason my examples use '?http' instead of just '?' but there are still potential pitfall situations even with '?http'
