Question: I'm changing my site to show friendly URLs like this:

```
www.example.com/folder/topic

```

Works fine!

But when I add a parameter to the URL:

```
www.example.com/folder/topic?page=2

```

`$_GET` stops working. It doesn't recognise the parameter at all. Am I missing something? The parameter worked fine before using full URLs.

Answer: 
If it's a mod\_rewrite problem, which it sounds like, you could add the `[QSA]` flag to your mod\_rewrite rule, to append the query string to the rewritten URL instead of throwing it away.

Your rule will end up looking like:

`RewriteRule from to [QSA]`
If you want to make your PHP URLs "friendly" you need to use something like Apache's mod\_rewrite. Google something like "apache mod\_write friendly url" and you will get plenty of articles on the subject.
