Is there a simple PHP development server?
<p>When writing web apps in Python, it brain dead easy to run a development server. Django and Google App Engine both ship with simple servers. </p>

<p>The main feature I'm looking for is no configuration. I want something like the GAE dev server where you just pass the directory of the app as a parameter when the server is started.</p>

<p>Is there a reason that this is more difficult with PHP?</p>
