new to php - hello world
<p>I am new to PHP - just downloaded it and wrote hello world program:</p>

<pre><code>&lt;html&gt;
&lt;body&gt;

&lt;?php

$fileName = "test.jpg"; 

$txt="Hello World!";
echo $txt;

?&gt;

&lt;/body&gt;
&lt;/html&gt;
</code></pre>

<p>But it doesnt work. I named the file test.php and opened it with Firefox and nothing was displayed.</p>
