<p>I'd like all queries like</p>

<pre><code>http://mysite.com/something/otherthing?foo=bar&amp;x=y
</code></pre>

<p>to be rewritten as</p>

<pre><code>http://mysite.com/something/otherthing.php?foo=bar&amp;x=y
</code></pre>

<p>In other words, just make the .php extension optional, universally.</p>

Something like...
```
```
RewriteRule /something/(.+)?(.+) /something/$1.php?$2
```
```
would probably work.
