PHP include files with periods in file name
<p>Is there a problem with some versions of PHP and file names which look like this:</p>

<pre><code>report.class.php
</code></pre>

<p>I tried to use one and it failed once and worked once, but I can't replicate the failure. So I'm not sure exactly what the cause is, prefer using the period-separated filenames, but would strongly prefer not to be using "fragile" file names on my site.</p>
