Extra characters after echo in php
<p>Getting started in PHP, but even with a "Hello world" I'm running into problems ...</p>

<p>Here's my page:</p>

<pre><code>&lt;html&gt;
  &lt;body&gt;
    &lt;?php 
        echo "&lt;p&gt;Hello world.&lt;br /&gt; &lt;/p&gt;" ;
    ?&gt;
  &lt;/body&gt;
&lt;/html&gt;
</code></pre>

<p>But instead of just 'Hello world.' I get</p>

<pre><code>Hello world.

" ; ?&gt; 
</code></pre>

<p>What gives? </p>

<p>FWIW, I'm using XAMPPlite (which is an Apache 2.5.8 with a PHP 5.3.1 on Win XP).</p>
