Do you need to decrypt the query string first ?

yes - if you have a query string like 4509134534068953534875104584437043134081743 or whatever then php won't turn it into a $_GET var. although your query string could contain &'s and/or ?'s and/or ='s in which case you might have cruft in the $_GET array which you would want to clean out before extracting your decrypted string into $_GET ..

decrypt($_SERVER['QUERY_STRING']); Once you have decrypted it, can you pass it along to a $_GET as you would with an unencrypted query string ? $test = $_GET['test']; Or, do you need to parse the string to extract variables?

yes you do, but this being php - there is a function that will do it for you :-) http://php.net/parse_str

many thanks g
