I had a hard time interpreting your question, but I think you're saying that you are generating URLs like this: /page.php?foo1=bar1&foo2=bar2&foo1=bar3&foo2=bar4 And, you're wanting to not duplicate variables in your URL, correct? You could always keep your query string in an array or something. This would allow you to update values in the array prior to the end of your script. You can start this array using $_GET: $query = $_GET; Of course, you might want to rather filter this data on each page, so that you don't spread tainted data more than necessary. Regardless, this will allow you to update values in your query string. If you want to update foo1, you don't have to care whether it's already set: $query['foo1'] = 'newvalue'; Hope that helps.
